- 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.
Fixed sidebar width (never concedes), figma session-row rail (16px twist +
status slots, triangle arrows, mount fade), exact brand wordmark svg with
tooltip'd rail controls, form controls inheriting the app font stack, and
inlined the twist button reset since the tsdown CSS pipeline drops composes.
