Mechanical fixes from `npx impeccable detect`:
- Sidebar.svelte: replace `transition: width, min-width` on the aside
with a wrapping CSS-grid container animating `grid-template-columns`.
Avoids per-frame layout cost from animating `width` directly.
- MorningTriageModal.svelte: swap pure `bg-black/50` overlay for the
brand deep-neutral `rgba(26, 24, 22, 0.5)` (#1a1816 @ 50%). TODO left
in source to promote this to a `--color-overlay` token in app.css.
- Toggle.svelte: drop bouncy `cubic-bezier(0.34, 1.56, 0.64, 1)`
(1.56 overshoot) for ease-out-quart `cubic-bezier(0.16, 1, 0.3, 1)`.
Still snappy, no overshoot — better fit for a toggle.
- TasksPage.svelte: same grid-template-columns refactor as Sidebar
for the list-sidebar `transition: width` declaration.
Verification:
- npm run check: 1 pre-existing error (vite.config.js:5), 1 unrelated
warning in SettingsGroup (out of scope, owned by parallel subagent).
- npm run build: clean.
- cargo clippy --all-targets -- -D warnings: clean (with LIBCLANG_PATH).
- cargo test --workspace: 283 passed, 0 failed.
- cargo fmt --check: pre-existing diffs in main.rs / lib.rs (no Rust
files were touched in this commit).
Manual smoke deferred — `npm run dev` is in use by the SettingsPage
subagent, so the build-clean signal is the proxy.
