Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR adds Toast and changes Button interaction and rendering. At the current head, detached Toasts can retain auto-dismiss timers, focused buttons can hide their labels, hover animation can continue scheduling redraws indefinitely, and custom padding or borders can misplace content; related tests also leak timers or use an invalid spy. These are concrete runtime and UI correctness risks, so the PR is not merge-ready until fixed or explicitly accepted. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Disable auto-dismiss in the render helper to stop real timers from leaking.
renderToast does not set duration, so every Toast built by the Unicode and ASCII blocks starts a real 3000ms timer. Those blocks do not use fake timers and never call dismiss(). Nine timers stay pending after the tests finish. They keep the worker alive and can fire dismiss() after teardown.
Default duration to 0 in the helper. Tests that need the timer set it explicitly.
💚 Proposed helper change
function renderToast(
opts: ConstructorParameters<typeof Toast>[0],
style: ConstructorParameters<typeof Toast>[1] = {},
width = 30,
height = 5,
) {
- const toast = new Toast(opts, style);
+ const toast = new Toast({ duration: 0, ...opts }, style);
const screen = new Screen(width, height);
toast.updateRect({ x: 0, y: 0, width, height });
toast.render(screen);
return { toast, screen };
}Apply the same change at Line 226, which also constructs a Toast with the default duration outside a fake-timer scope. Wait — Line 226 sits inside the Toast — auto-dismiss behavior block, which does install fake timers, so it is safe.

Override unmount() and destroy() in Toast. Clear _timer before delegating to the base implementation. The base destroy() does not invoke an overridden unmount(). Otherwise, the timer can call dismiss() after detachment and keep the Node event loop alive until duration expires.

Use _getContentRect() while preserving the manual border inset.
Toast leaves style.border unset, so _getContentRect() accounts for padding but not the manually drawn border. Use its result and add the one-cell border inset before rendering content. This makes style.padding overrides effective without placing content against the border.
The current geometry leaves no content at heights 3 or 4. With padding 1 and a one-cell border, those heights cannot contain content; define compact-toast behavior and add tests for it.

Assert the focused border colors and press redraw.
The focused content cell uses white for both fg and bg. Assert the focused border cell has fg: cyan and bg: white; the current bg check also passes when unfocused.
Use fake timers for startPress(), advance past 16 ms, and assert that markDirty() was called.

Keep focused button text visible.
default and ghost use a white hover background. Their foreground color is also white in FG_COLORS. A focused button therefore renders its label invisibly.
Use a contrasting hover background or define a contrasting hover foreground for these variants.

Mark the widget dirty when animation state changes.
startHover() and startPress() change visible state but only request a redraw through a delayed timer. Call this.markDirty() after setting each start time. This gives keyboard activation and hover changes an immediate redraw.
Proposed fix
this._hoverStartTime = Date.now();
+ this.markDirty();
this._scheduleAnimation();
this._pressStartTime = Date.now();
+ this.markDirty();
this._scheduleAnimation();📝 Committable suggestion

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Stop scheduling redraws after the hover animation completes.
After _getHoverProgress() reaches 1, it stays positive because _hoverStartTime is retained. isAnimating then remains true and this code schedules a new 16 ms timer after every render while the button is focused.
Only schedule while hover progress is below 1. Keep the completed hover state for color selection.
Proposed fix
const hoverProgress = this._getHoverProgress();
const pressProgress = this._getPressProgress();
-const isAnimating = hoverProgress > 0 || pressProgress > 0;
+const isHoverAnimating = hoverProgress > 0 && hoverProgress < 1;
+const isAnimating = isHoverAnimating || pressProgress > 0;Also applies to: 260-265

Blocking — Toast.ts (widgets) duplicates the existing ui/src/Toast.ts; bun.lock/package.json downgrade vitest ^4.1.8→1.6.0 + add vite 5.4.0 repo-wide (breaks the toolchain); vitest.config.ts gets a BOM; and Button.ts is fully rewritten — unrelated scope creep. Scope to just the new widget (non-colliding name); drop the toolchain/Button changes. |
