/* LIVE-DRINK dashboard. A measurement instrument, not a product page: neutral paper, hairlines, ink, and
   colour reserved for the outcome of each DRINKRANK decision.

   Colour roles (validated with the dataviz six-checks script, --pairs all, both modes):
     --tp / --fp / --fn  categorical slots 1-3 (blue, orange, aqua). Light aqua is 2.74:1 on the surface, so
                         every outcome also carries a text label and a distinct marker shape (relief rule).
     --tn / --other      neutral: TN is assumed from silence, the rest are not in the 2x2.
     --good / --warning  status only (pipeline health), always with an icon and a word.
   Radius system: panels 8px, everything interactive or chip-like 6px. No shadows. */
