Closes https://github.com/pingdotgg/t3code/issues/25446

What it fixes

The desktop window can't get smaller than 840x620, so it doesn't fit a half or quarter screen tile. Windows snap and macOS tiling leave it too big, and Linux tiling crops it. This PR lowers the minimum to 400x360, and a narrow window keeps its size after a restart.

It also fixes what broke at that size. Settings rows wrap. In short windows the new-thread composer and its notices stay on screen. Settings and the command palette open below the window's own close and minimize buttons.

Re-lands https://github.com/pingdotgg/t3code/pull/27802, which re-landed https://github.com/pingdotgg/t3code/pull/19232 (reverted in https://github.com/pingdotgg/t3code/pull/22222).

Evidence

Before is main, after is this PR. Both are real desktop builds.

Windows, snapped to half the screen. Before, the window stays 840 wide and runs past the half.

BeforeAfter

Windows, dragged to its smallest size. Before stops at 840x620, after at 400x360.

BeforeAfter

macOS, quarter tile. Before on the left, after on the right.

Linux, half tile. Before on the left: the right edge, with the header buttons, is cut off. After on the right.

A narrow window comes back the same size after a restart.

Settings and the command palette at 400x360 open below the window buttons.

Walkthrough

The desktop minimum window size is reduced to 400×360 DIP, with settings tests covering invalid and persisted bounds. Web layouts account for native titlebar height and adjust modal, command-dialog, draft-composer, heading, and settings controls at narrow or short viewports.

Changes: Desktop window sizing

Layer / File(s)Summary
Minimum window bounds
apps/desktop/src/settings/DesktopAppSettings.ts, apps/desktop/src/window/DesktopWindow.ts, apps/desktop/src/settings/DesktopAppSettings.test.ts
The minimum window size changes to 400×360, and window creation uses the shared setting. Tests cover invalid bounds and reloading saved 400×360 bounds and maximized state.

Web responsive layouts

Layer / File(s)Summary
Titlebar-aware overlays
apps/web/src/components/AppRouteModal.tsx, apps/web/src/components/ui/command.tsx
The route modal and command dialog use native titlebar height in their top spacing. The route modal also adds a matching draggable strip.
Short-viewport chat layout
apps/web/src/components/ChatView.tsx, apps/web/src/components/chat/DraftHeroProjectHeading.tsx
At short viewport heights, the draft-hero composer aligns to the bottom and detached draft banners take space above it. The introductory heading is visually hidden at heights of 28rem or less.
Wrapping settings controls
apps/web/src/components/settings/SnoozePresetsSettings.tsx, apps/web/src/components/settings/TypographySettings.tsx
Snooze preset controls can wrap. Typography controls wrap and switch to a non-wrapping layout at the 32rem settings-row breakpoint; the font-family control has a 9rem minimum width.

Estimated code review effort: 3 (Moderate) | ~25 minutes

  • 29512 — The change allows narrow desktop bounds to persist, but it does not address restoring sidebar width after a narrow startup viewport.

Keep the modal below caption buttons at sm widths.

In a 700×360 Windows window, sm:p-6 places the modal at y=24, while the native caption is 40px high. The Usage close button overlaps the caption buttons, so a click on its upper edge can activate a window control instead. Apply the titlebar inset at sm widths too. (raw.githubusercontent.com)

✅ Addressed in commit ad42e64

[Opus 5.5][Claude Code] on behalf of shivam.

Valid. main already has this at 840–1023 px wide, and this PR makes 640–839 reachable too. Fixed in ad42e648d20c9b39be537c5c1beca4049f64a320, though not by adding padding inside the card: the backdrop's top inset between sm and lg is now max(1.5rem, native titlebar height). At 700x360 with a 40 px caption strip the modal starts at y=40 and its close button at y=51 (52/63 with macOS' 52 px). lg (40 px) and plain web (24 px) are unchanged.

@shivamhwp The supplied code confirms the fix. DialogPrimitive.Viewport now applies max(1.5rem, nativeTitlebarHeight) as its top padding from sm to below lg. This moves the modal below the caption strip without adding padding inside the card. No further change is needed for this finding.

Use an important height override for the trailing ?.

When data-inline=true at the lg breakpoint, the lead-in becomes screen-reader-only at heights of 448px or less. The project name and trailing ? remain visible, so the heading can render as demo?.

A plain [@media(max-height:28rem)]:hidden does not reliably override lg:group-data-[inline=true]/draft-hero:inline. The group-data selector has higher specificity. Use the important utility:

[Opus 5.5][Claude Code] on behalf of shivam.

Valid: at 1200x400 the heading read server? with the lead-in screen-reader-only. Fixed in ad42e648d20c9b39be537c5c1beca4049f64a320 with [@media(max-height:28rem)]:hidden! on the trailing ?. It now reads server at 1200x400 and What should we build in server? at 1200x800.

@shivamhwp Thanks for the fix. The supplied code includes [@media(max-height:28rem)]:hidden! on the trailing ?. This addresses the display override conflict. Your reported checks cover both short and tall inline layouts.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The desktop minimum window size drops to 400×360, with responsive layout adjustments for smaller windows. This changes the product's enforced resizing defaults and requires human confirmation; initial window dimensions remain unchanged.

ran separate main and pr checkouts with vp i, one server at a time, isolated T3 homes, real Chrome through repository Playwright, and real production Electron builds on Linux X11. created narrow-window-verification and its git repository through the app. used the same project data for comparison. real Codex gpt-6.1-sol turns completed on main web, pr web at 400x360, and pr Electron at 400x360; each ran pwd and git status --short. no replay provider, mocks, fixtures, or demo data.

  • reproduced main: requesting a native 400x360 window stops at 840x620. pr reaches exactly 400x360.
  • pr preserves main's saved 1100x780 window at (100,100), saves and reopens 400x360 at the same location, and maximizes/restores back to 400x360.
  • at 400x360 and 700x360, settings opens below the 40px native caption strip. real clicks close settings while the same Electron process stays running. the palette starts at y=48 at 400x360.
  • typography and snooze controls wrap at 400x360. changed font size 16→17→16 and snooze duration 1→2→1 through their controls. the short 1200x400 draft has no trailing question mark.
  • stopped the real server with a 400x360 draft open: its reconnecting notice remains visible at y=306–344. restarting reconnects and removes the notice.
  • both desktop builds succeeded on Blacksmith. the existing DesktopAppSettings.test.ts passed all 12 tests there. current head CI has 33 successful checks, zero pending or failing.

Not verified

macOS and Windows native controls, snap/tiling, and persistence; Wayland compositor tiling or scaled displays; native iOS/Android; packaged installers or updates; every rate-limit/fallback notice variant. this VM provides Linux X11, so native resize constraints were exercised directly rather than claiming a Wayland tiling test.

Electron needed --password-store=basic and --disable-gpu on this VM; its default secret-store startup stalled before that workaround. the remote build worker needed libsecret-1-dev. these were environment setup changes, not PR changes. uploaded recording playback and seeking were checked in T3's player. all task-owned dev and Electron servers were stopped afterward.

takeover update

all 32 checks are green on d2417dfbd2f62bd310dc277c5d5555abc98c1058. github reports no conflicts; both review threads are resolved. ready for Maria's review.

merged github/main (8760d063e903) with a merge commit, without rebasing. resolved the composer conflict by keeping main's child-thread approvals before the relative composer wrapper, preserving the short-window notice layout. pushed d2417dfbd2f62bd310dc277c5d5555abc98c1058 to the existing fork branch without force. the pr remains nine files.

vp run check:changed passed on blacksmith: format, lint, both knip checks, affected typechecks, 88 focused tests across eight files, and six compiler checks. two independent scoped reviews approved this head. both existing bot review threads are resolved.

fresh chrome verification at 400x360: opened a project draft, opened appearance settings, and closed settings back to the draft. this pass did not repeat the earlier native electron or provider runs recorded above.
