This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. # Releases ## @sveltejs/kit@2.58.0 ### Minor Changes - breaking: require `limit` in `requested` (as originally intended) ([#15739](#15739)) - feat: `RemoteQueryFunction` gains an optional third generic parameter `Validated` (defaulting to `Input`) that represents the argument type after schema validation/transformation ([#15739](#15739)) - breaking: `requested` now yields `{ arg, query }` entries instead of the validated argument ([#15739](#15739)) ### Patch Changes - fix: allow `query().current`, `.error`, `.loading`, and `.ready` to work in non-reactive contexts ([#15699](#15699)) - fix: prevent `deep_set` crash on nullish nested values ([#15600](#15600)) - fix: restore correct `RemoteFormFields` typing for nullable array fields (e.g. when a schema uses `.default([])`), so `.as('checkbox')` and friends work again ([#15723](#15723)) - fix: don't warn about removed SSI comments in `transformPageChunk` ([#15695](#15695)) Server-side include (SSI) directives like `<!--#include virtual="..." -->` are HTML comments that are replaced by servers such as nginx. Previously, removing them in `transformPageChunk` would trigger a false positive warning about breaking Svelte's hydration. Since SSI comments always start with `<!--#` and Svelte's hydration comments never do, they can be safely excluded from the check. - Change enhance function return type from void to MaybePromise<void>. ([#15710](#15710)) - fix: throw an error when `resolve` is called with an external URL ([#15733](#15733)) - fix: avoid FOUC for CSR-only pages by loading styles and fonts before CSR starts ([#15718](#15718)) - fix: reset form result on redirect ([#15724](#15724)) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>

Temporary revert to verify the FOUC fix in 2.58.0 (sveltejs/kit#15718) is what's causing Percy snapshots to capture unstyled content after client-side navigation.

SvelteKit 2.58.0 (sveltejs/kit#15718) emits root-layout stylesheets in the server HTML to avoid a flash of unstyled content. With `paths.relative: true` (the default), those hrefs are relative to the request URL. Percy preserves the attribute strings verbatim and renders the snapshot at a different URL, so the relative hrefs no longer resolve and the snapshot comes out unstyled. Force absolute paths under `PLAYWRIGHT=1` to keep Percy snapshots stable.

closes #13307
related to rust-lang/crates.io#13436
This PR ensures that stylesheets and fonts are eagerly loaded even if SSR is disabled. This helps prevent FOUC. In the case of fallback pages, we only load the root layout which already applies to every page and is safe to load even if we don't know what route is being rendered until CSR kicks in.
