   live-picker.css — Ζωντανή Μάχη · «Διάλεξε ύλη» reimagined
   lp-* classes only. Tokens come from css/tokens.css (--card/--line/--fg/
   --muted/--sink/--disp/--sans/--serif …); the live accent is --ca on .lp
   (.has-accent derives --ca-mid/--ca-ink/--ca-tint). Per-subject accent
   is --sa, set inline per box/row. Selected states use the platform's
   fixed green (#2e9e4f), same as the syn-* mix chips.
