Root-cause find: the sidebar 'highlighting' on ←/→ was :focus-visible —
pointer-clicked elements match it only after a keypress, so any key in
the quiz lit the still-focused session row. The arrows never moved
focus. Fix: the no-ring law (owner) — *:focus/:focus-visible outlines
removed app-wide in globals.css; surfaces keep their own affordances
and the dock's keyboard walk keeps its ring utilities.
Slider repairs:
- mousedown-preventDefault had killed click + drag in Chromium —
removed (with tabIndex -1); the slider is natively interactive again,
and the ring law makes its focus invisible anyway.
- Focused arrows step the STOP index on the input itself (native would
step 1% and snap straight back — dead keys); the global handler
skips INPUT targets, so no double-step. Enter still submits.
- Empty side: var(--muted) matched the card and vanished — now #141414
(the owner's main-background pick), and the pill carries a border
again (border-border).
- Dashed tick per snap stop below the bar, inset by the thumb's
half-width so each tick sits under the thumb's center at that stop.
