Menus: keep 12px viewport clearance with internal scroll, pin workspace
create actions in a footer, and pre-render portal lists hidden so the
first painted frame is already at its final position (no open jump).
Tool rows: 14px icons, secondary titles, no hover fill, and a hover
chevron preview on in-place expandable rows. Settings: 800x600 layer-2
panel over a blurred mask, hover states, and wrapping selector cubes;
ModelSelect surface tokens now match the Menu primitive.
- The real-browser collapse smoke tracked the old chrome: visible HARNESS
text (the wordmark svg is aria-hidden now), an 'Expand sidebar' label
(renamed 'Open sidebar'), a 300px settle (default is 280), and an
immediate focus assert (rail search defers focus past the slide). The
case now tracks the brand span, polls the deferred focus, and uses the
current labels and width.
- Tooltip treated hover and focus as one trigger: leaving with the mouse
dropped the bubble of a still-focused anchor (and vice versa). The two
triggers are tracked independently; the bubble hides only after both
clear. Spec pins both orders.
- The ui-sidebar README and the bilingual collapse note still described
the retired geometry morph; both now state the slide + crossfade
contract, the fixed-width (never-conceding) sidebar, and the rail's
whale-mark/tooltip chrome.
