/* ================================================================
   FOCUS-END.CSS — the screen after a chosen concept or graph area ends
   (../practice/focus-end.js, Seth 2026-10-14): learned → keep studying it /
   the AI's next pick / build on it; not ready → a prerequisite / keep at it;
   an area → keep at it / an area you haven't practised.

   A CROSSROADS, IN THE LIST'S VOICE. The head is the concept's name in the
   home's numeral face (--xp-display, Instrument Serif) at display size, its
   meter the "Or choose a concept" list's (concept-choice.css .cc-bar) drawn
   thicker. Below it the ways forward stand side by side as cards — the one
   the model favours (`--lead`) washed and ruled in the accent — and every
   option inside is a ledger row with its own meter, so strength is read the
   same way everywhere on the screen. Tone (data-tone) only tints: cyan for
   learned (`up`), amber for not ready (`wall`), muted for out of questions.

   Token-first, no hex (styles/watch.py).
