…d+K palette & UI consistency pass (NousResearch#38631)

* fix(desktop): surface background-session clarify prompts instead of hanging

clarify.request is a one-shot blocking event: the gateway turn blocks on
clarify.respond. The desktop handler dropped it for any non-focused session
(`if (!isActiveEvent) return`) and stored at most one request in a single
global atom, so a background session that asked a clarifying question hung
forever and re-focusing it could never recover (the event was already gone).

- store/clarify.ts: key pending requests by runtime session id; expose the
  active session's request via a focus-scoped computed view (ClarifyTool is
  unchanged). clearClarifyRequest takes an optional session id for targeted
  clears, with a request-id fallback.
- use-message-stream.ts: park every session's clarify (drop the isActiveEvent
  early return); toast when one lands for a background session since the row
  otherwise just keeps spinning like normal work.
- clarify-tool.tsx: clear by session id so answering one chat can't wipe
  another's pending request.
- store/clarify.test.ts: concurrent independence, focus-scoped view,
  targeted/stale/fallback clears.

* feat(desktop): persistent needs-input indicator + icon button consolidation

Replace the background-clarify toast (expired on alt-tab, easy to miss) with a
persistent, glowing amber "needs input" dot on the session's sidebar row,
driven off a new ClientSessionState.needsInput flag mirrored into a
$attentionSessionIds store. The flag is set on clarify.request and cleared the
moment the turn resumes (tool.complete) or ends.

Also: redesign the clarify tool UI (borderless choices, pseudo-radio dots,
right-aligned checkmark, arc border, tighter padding), make Button the single
source of icon-button styling (4px radius, new icon-titlebar variant, titlebar
buttons rendered polymorphically via asChild, Codicons throughout), put the
file-tree refresh action first, and .trim() pasted composer text.

* style(desktop): padding-driven, square non-icon buttons

Default button sizing was vanilla-shadcn chunky (fixed h-9, 16px padding) and
inconsistent with the icon-button radius pass. Size text variants by
padding + line-height instead of fixed heights so they stay snug and scale
with content, and drop the radius on non-icon buttons (icon buttons keep the
shared 4px). Move the update-overlay CTAs off a hardcoded h-10 onto the
padding-based lg variant. Composer and the inline approval strip are untouched.

* style(desktop): shrink button scale, flush overlay sidebar, variant-ize stray buttons

- Buttons: smaller default font (14px -> 13px) and tighter padding-driven sizes
  across every variant; the chunky shadcn scale read as oversized in a dense
  desktop UI.
- Overlay split layout (settings / command center): the shared OverlayView top
  padding left the card surface showing as a gap above the sidebar. Move the
  titlebar clearance into each column so the sidebar background runs flush to
  the card's top edge.
- Consolidate buttons that hardcoded size/radius/font onto the proper size
  variants (tooltip-icon-button, overlay close, cron IconAction, SidebarTrigger,
  gateway system button, session-row actions radius, title chip radius, release
  notes link) so styling flows from variant props, not per-call overrides.
  Composer and the inline approval strip are intentionally left as-is.

* style(desktop): 12px button text, drop sparkle decoration + redundant settings titles

- Button base font down to 12px (text-xs) for the dense desktop scale.
- Remove the decorative Sparkles glyph from the model "Apply" button (keep the
  spinner while applying).
- Drop the page-level section titles that just restate the left nav ("Main
  model", "Appearance", "MCP servers") — the sidebar already labels the pane.
  Sub-section headings (Auxiliary models, LLM providers, etc.) stay.

* feat(desktop): add boxless `text` button variant; use for aux-model actions

New reusable `text` variant renders a button as inline label text (no
bg/border, muted -> foreground, underline-on-hover affordance). Emphasize the
actionable word by adding `font-semibold`/`underline` at the call site. Applied
to the auxiliary-model "Set to main" (plain), "Change" and "Reset all to main"
(bold + underlined) actions, replacing the boxed ghost/outline buttons.

* style(desktop): nudge button scale up + 2.5px radius on non-icon buttons

Bump default/sm vertical padding a step (the 12px pass read too small) and give
non-icon buttons a subtle 2.5px radius instead of square corners. Icon buttons
keep their 4px.

* style(desktop): unify Input/Textarea/SelectTrigger on shared controlVariants

Mirror the buttonVariants exercise for non-composer form controls: add a
single controlVariants source of truth (2.5px radius, 12px text,
padding-driven sizing, chrome via desktop-input-chrome) and consume it from
Input, Textarea, and SelectTrigger. Drop per-call radius/height/font
overrides that fought the shared look.

* style(desktop): flatten appearance settings — drop card-in-card sections

Remove the outer card chrome (border/bg/shadow/rounded) wrapping each
appearance section so they're flat headings + option grids instead of
boxes nested inside boxes, matching the other settings pages.

* style(desktop): de-box appearance options into flat rows + bare theme swatches

Color Mode and Tool Call Display become flat radio-style rows (no tile
border/fill, no inner icon box, no filled check badge — just a subtle active
bg and a check). Theme drops its outer card wrapper so only the preview
swatch shows, with a primary ring marking the active palette.

* style(desktop): primitive-level pointer cursor + borderless settings lists

Add a base-layer rule giving every interactive control (button, select,
menu item, switch, tab, summary) cursor:pointer, and strip the now-redundant
hardcoded cursor-pointer from those elements (plain clickable divs/labels
keep theirs). Remove the divide-y separators from settings list sections so
they breathe.

* style(desktop): Color Mode + Tool Call Display as one-row segmented controls

Replace the vertical option-row lists with a compact SegmentedControl
(grouped pill buttons on a single track), dropping the per-option
descriptions since the section subtitle already covers the context.

* style(desktop): drop redundant On/Off label next to boolean config switches

The switch already communicates state, so the text label was noise.

* style(desktop): add Switch xs size; move appearance controls inline-right

Add an xs size variant to the Switch primitive and use it for the provider
edit submenu toggles. In appearance settings, drop the redundant selection
Pills (the UI already shows the active choice), move the Color Mode and Tool
Call Display segmented controls into the section header's right side
(responsive: stacks under the heading on narrow widths), and shrink the
segmented control.

* feat(desktop): titlebar toggle to flip sidebar sides

Adds a top-left swap button (replacing the search icon) that mirrors the
layout: sessions sidebar ↔ file browser + preview rail. Persisted via
$panesFlipped. The left/right sidebar toggles, content inset, and pane
borders all follow the active side so the buttons stay accurate after a flip.

* feat(desktop): global Cmd+K palette + UI consistency overhaul

Builds on the clarify/needs-input work with a cross-cutting pass to make
the desktop surfaces feel like one app.

- Global Cmd+K command palette (cmdk): nav, settings deep-links, async
  API-key / MCP-server / archived-session groups, reusable theme sub-page
  (light/dark groups, stays open on pick), loop nav, fuzzy match. Replaces
  per-page settings search.
- Shared SearchField: borderless, underline-on-focus, `field-sizing`
  auto-width. Unifies sessions sidebar, pages, overlays, command center,
  cron; drops bespoke OverlaySearchInput.
- Cron & Profiles converted to OverlayView; flat token-driven panels
  (no card-in-card / divider borders) matching command center.
- `r` refresh hotkey via useRefreshHotkey; drop the visible refresh buttons.
- Button text/textStrong link variants applied across settings & views;
  shared PAGE_INSET_X content gutters.
- Math/ascii loaders replace "Loading…" text placeholders; x-icon close
  over text "Close"; cursor-pointer at the dropdown/select primitive level.

* style(desktop): tidy root error-boundary actions

Reload window → text link, Open logs pushed right (ml-auto), and the
error message box drops the oversized rounded-2xl for rounded-md.

* style(desktop): fix profiles sidebar — header + add-icon, drop text-link

The full-width `text` New-profile button drew an underline under the +
glyph on hover (text-decoration spans the icon). Replace with a proper
"PROFILES" section header + ghost add-icon button, matching the chat
sidebar's header/new-item pattern.

* style(desktop): kill focus rings globally

Tab/focus showed Tailwind's `focus-visible:ring-*` (a box-shadow) plus the
native outline. Drop both via an unlayered reset that nulls --tw-ring-*;
the composer / input soft-glow is untouched (those use direct box-shadows).

* style(desktop): shared Badge component; tidy profile metadata

Add a proper shadcn-style Badge (CVA tones, app radius — not a full pill)
and use it for the Default/.env tags instead of bespoke rounded-full spans.
Drop the oversized text-sm metadata values to text-xs.

* style(desktop): migrate bespoke pills to shared Badge; tidy cron/titlebar

- Sidebar toggles in the titlebar no longer carry an active highlight —
  they're plain show/hide affordances now.
- Replace every bespoke rounded-full status pill (cron, messaging,
  settings, skills) with the shared Badge (adds a `warn` tone). App radius,
  one component.
- Cron row actions use Codicons (play/debug-pause/zap/edit/trash) to match
  the rest of the chrome instead of stray lucide glyphs.

* style(desktop): drop active background on titlebar actions

Mute/haptics state reads from the icon glyph (and aria-pressed) — no
background highlight on any titlebar action.

* style(desktop): tighten error-boundary action gap

gap-4 → gap-2.5 between Try again / Reload window.

* style(desktop): hide search when there's nothing to search

Empty datasets no longer render a search field. Adds a `searchHidden` prop
to PageSearchShell (artifacts/skills/messaging) and gates cron + command
center sessions search on a non-empty list. The chat sidebar already did
this via showSessionSections.

* fix(desktop): composer wraps long text & expands at the real wrap point

Long unbroken input ran off horizontally and the stacked layout flipped
on a char-count guess (too early). Add wrap rules to the contentEditable
and drive expansion off the editor's actual rendered height via the
resize observer, so it stacks exactly when the text wraps to a 2nd line.

* feat(desktop): composer/intro polish + shared ErrorState

- Composer single-line row centers (was bottom-aligned); placeholder
  randomizes per session (starter vs follow-up) without mid-stream flip.
- Drop chat header on brand-new sessions (dead label + border).
- ⌘N flashes its sidebar hint; ⌘. toggles the command center.
- Intro wordmark fills width (drop 8rem fit cap).
- Unify error states on a shared ErrorState component (boundary + updates).

* style(desktop): satisfy lint across PR-touched files

* refactor(desktop): DRY/elegance pass over PR-touched files

- Shared useDeepLinkHighlight hook collapses 3 near-identical settings
  deep-link effects (keys/mcp); config kept inline (distinct bail-clear).
- command-center: table-driven SECTION_ICONS + single errorText helper.
- clarify-tool: OPTION_ROW_CLASS + RadioDot extracted from option rows.
- desktop-controller: merge Cmd+K / Cmd+. into one keydown handler.
- statusbar-controls: hoist shared action class.
- Misc: drop redundant cn()/cursor-pointer/dead fields; tidy switch.

* feat(desktop): Cmd+K jumps to sessions; drop API-key entries

Add active sessions to the palette (fuzzy jump-to-chat), remove the
low-value per-API-key entries, and move the lazy palette sources
(config/sessions/archived) to react-query instead of hand-rolled
useState + effect fetching. Hoist the shared nav helper.

Overlays/dialogs/toasts share a custom shadow-nous (downward-weighted) and
--stroke-nous hairline instead of hard borders: boot-failure, install,
notifications, model-picker, onboarding, prompt-overlays, updates, Dialog.

- button: outline is a 1px inset ring (no fill/shadow); chrome lives in Button
- BrandMark: 256px nous-girl mark replaces sparkle glyphs (updates/onboarding/about)
- onboarding: conditional header, lemniscate-bloom loaders, OTP device-code boxes,
  NOUS CONNECTED hero (ascii decode) + cuneiform easter egg, "Begin" matrix exit
- shared LogView + ErrorState; math/ascii loaders over "Loading..." text
- appearance-settings flattened to SegmentedControl/ListRow; keybind-panel on
  shadow-nous + text-variant reset
- restore flat-UI clobbered by #38631's stale-squash (4a1907b): command-center,
  profiles, skills, messaging, cron de-boxed; shared SearchField + PAGE_INSET_X;
  profiles back on OverlaySplitLayout; skills tabs+search one row, no row dividers

…redesign (#40708)

* fix(desktop): unify dialog/overlay buttons on shared Button component

Replace raw <button> action/text controls across the modal layer (boot
failure, install, update, onboarding, clarify, model-visibility,
notifications, gateway menu) with the shared Button + its variants
(text / ghost / icon-xs). Drops the bespoke square-cornered styling so
every dialog matches the app's slightly-rounded button system, and
swaps clarify-tool's hardcoded "Skip" for the existing i18n string.

* feat(desktop): add dev-only dialog gallery for auditing overlays

A code-split, DEV-gated harness (toggle ⌘/Ctrl+Alt+Shift+D) that triggers
every dialog/overlay so their buttons can be eyeballed in one place:
store-driven overlays (boot failure, updates, notifications, sudo/secret)
plus in-place dialogs (confirm, profile create/rename, attach-url, model
picker/visibility, clarify, tool approval). Never ships to production.

* fix(desktop): use Ctrl+Shift+D for dialog gallery (mac-friendly)

The Cmd/Ctrl+Alt+Shift+D chord is impractical on macOS (Option mangles
the keypress). Ctrl+Shift+D is the same chord on every platform and uses
neither Cmd nor Option.

* fix(desktop): stop overriding button icon size to size-4

Action buttons hardcoded size-4 icons, overriding the Button component's
built-in size-3.5. That extra 2px is why boot-failure / onboarding / gateway
buttons looked chunkier than the settings "Apply" (size-3.5 spinner) despite
being the same component+size. Drop the overrides so icons inherit 3.5.

* feat(desktop): add BrandMark, use it in the updates overlay hero

New BrandMark renders the white logo.png on a hardcoded brand-blue tile
(#0000F2 light / #222 dark), replacing the generic Sparkles hero glyph in
the "update available" overlay. Trying it here first to iterate on the look.

NOTE: apps/desktop/public/logo.png is currently a 1x1 placeholder — the tile
renders now; the glyph appears once the real white logo art is dropped in.

* feat(desktop): add real logo.png asset, render it white in BrandMark

logo.png is blue line-art on transparent, so force it white via filter to
read on both the brand-blue (#0000F2) and near-black (#222) tiles. Bump the
glyph to 62% of the tile for the portrait aspect.

* fix(desktop): BrandMark renders logo as-is, no light bg/radius/padding

Drop the white filter, the hardcoded light-mode blue tile, the radius, and
the inner padding. Logo now fills the tile over a transparent surface in
light mode; dark keeps the #222 tile.

* fix(desktop): bump updates-overlay BrandMark to size-16

* feat(desktop): use downscaled karb.webp in BrandMark

Swap the BrandMark glyph to karb.webp, downscaled from 1129x1418/888KB to
254x320/81KB for the hero badge.

* feat(desktop): use nous-girl mark in BrandMark, invert in dark

Key the white background to transparent so only the black line-art remains
(384px/20KB webp). Light mode shows black art; dark mode flips it white via
dark:invert on the #222 tile. Drop the now-unused karb.webp and logo.png.

* fix(desktop): BrandMark uses nous-girl as-is (no transparent/invert)

The dark-mode invert read as a creepy negative. Use the opaque black-on-white
mark unchanged in both themes; drop the white-key, dark:invert, and #222 tile.

* fix(desktop): give BrandMark an explicit white bg tile

* fix(desktop): use nous-girl.jpg directly in BrandMark

* perf(desktop): downscale nous-girl.jpg to 256x256 (466KB -> 19KB)

* style(desktop): bump nous light --theme-secondary to 14% blue

* fix(desktop): outline button is transparent, not chrome-filled

The outline variant used bg-background (the chrome color), so on cards/overlays
with a different surface it rendered as an odd gray-blue fill (visible on the
boot overlay's Repair install / Use local gateway). Make it bg-transparent so
it inherits the surface like a real outline. Reverts the unrelated
--theme-secondary tweak.

* fix(desktop): clean outline button — thin border, no shadow/fill

Drop shadow-xs and the resting fills (light chrome bg, dark bg-input/30) so
outline is just a thin clean border with a subtle hover, in both themes.

* fix(desktop): stop forcing tertiary bg on outline buttons

A global [data-variant='outline'] rule set background: var(--ui-bg-tertiary),
which (attribute-selector specificity) overrode the cva bg-transparent — so
outline buttons always showed the pale tertiary fill on cards/overlays
regardless of the variant classes. Scope that fill to secondary only; outline
is now a true transparent border.

* style(desktop): unified overlay design system + restore #38631 flat-UI

Overlays/dialogs/toasts share a custom shadow-nous (downward-weighted) and
--stroke-nous hairline instead of hard borders: boot-failure, install,
notifications, model-picker, onboarding, prompt-overlays, updates, Dialog.

- button: outline is a 1px inset ring (no fill/shadow); chrome lives in Button

  profiles, skills, messaging, cron de-boxed; shared SearchField + PAGE_INSET_X;
  profiles back on OverlaySplitLayout; skills tabs+search one row, no row dividers

* refactor(desktop): clean pass — drop dead code, dedupe, fix stale docs

- log-view: drop unused `bare` prop + forwardRef (no caller uses ref)
- install-overlay: drop `stateOverride` (only the removed dev gallery used it)
- profiles: ProfilesViewProps down to { onClose } (drop vestigial section/titlebar)
- onboarding: hoist shared PROVIDER_ROW_CLASS (was duplicated 2x)
- brand-mark / error-state: tighten comments, fix stale AlertCircle reference
