MEDIUM — Double SafeArea padding when two banners are simultaneously visible (pre-existing, not introduced here)

accord_home.dart stacks the banners in a Column:

const UpdateBanner(),       // SafeArea(bottom: false)  ← new in this PR
const WebUpdatePrompt(),    // SafeArea(bottom: false)  ← new in this PR
const RolePreviewBanner(),  // SafeArea(bottom: false)  ← pre-existing
Expanded(child: body),

Flutter's SafeArea reads MediaQuery.padding.top but does not consume it from the widget tree. So if UpdateBanner and RolePreviewBanner are both visible on mobile (update available + user is in role-preview mode), RolePreviewBanner independently re-applies the full status-bar inset (~24–32 dp), giving it a redundant top gap.

Status: Pre-existing — RolePreviewBanner already used SafeArea(bottom: false) before this PR. This PR is consistent with that prior choice. Tracking as a follow-up: the clean fix is to lift the single SafeArea up to the Column level in accord_home.dart and strip it from each individual banner (using MediaQuery.removePadding or a wrapping SafeArea around a mainAxisSize: min Column that excludes the body). Scope is intentionally left for a separate PR.

LOW — WebUpdatePrompt's SafeArea is a no-op on web (harmless)

WebUpdatePrompt only ever renders when kIsWeb == true, where MediaQuery.padding.top == 0 (browsers have no overlapping OS status bar). The SafeArea(bottom: false) added here is harmless and keeps the widget consistent with its siblings. No change needed.

LOW — No tests for banner show/hide logic or SafeArea wrapping (fixed)

Commit 6aa84ce adds test/features/updates/update_banner_test.dart covering:

• Collapses to zero height when no update is available
• Renders banner text and SafeArea(bottom: false) when an update is available
• Collapses when dismissedVersion matches the release version
• Collapses when skippedUpdateVersion (settings) matches the release version
• WebUpdatePrompt renders nothing on non-web platforms

Summary

The core change — wrapping both banners in SafeArea(bottom: false) to match the pre-existing RolePreviewBanner pattern — is correct and consistent. The only fix committed here is the missing test coverage. The double-SafeArea edge case is pre-existing and low-impact enough to track separately.
