queen board: the task drawer's styles fail three website gates on main #1558

#1555 auto-merged on head f1939a3, one commit before the fix that makes the drawer's styles meet the board's gates.

So main (fe43439) carries the following failures:

• check:queen-direction: the health dot repeats the 'other' direction's grey #8a8a8a.
• check:queen-contrast: QueenTaskDrawer.css is a stylesheet the gate never measured. In addition, the drawer and its button sit on a thinned ground without a blur.
• check:queen-fallback-parity: six var() fallbacks disagree with the declared tokens.

Acceptance criteria

• npm run check:queen-direction, check:queen-contrast and check:queen-fallback-parity pass on main.
