   Hand-written, zero-build, zero-CDN. That is a deliberate architectural
   choice, not a shortcut: the interviewer app must run from a service-worker
   cache with no network at all, and a stylesheet fetched from a CDN is the one
   asset most likely to be missing at that moment.

     ------------------------------------------------------------------------
     Slot ORDER is the colour-blind-safety mechanism, not decoration: hues are
     assigned in this fixed order and never cycled. Validated in both modes on
     the adjacent pairlist — worst adjacent CVD ΔE 9.1 light / 8.4 dark,
     normal-vision ΔE 19.6 / 19.3, against surfaces #ffffff and #0f172a.

     Three light slots (aqua, yellow, magenta) fall below 3:1 against white, so
     the relief rule applies: every chart in this system ships visible direct
     value labels (see .result-row__pct and the chart label marks). Do not use
     these in a chart that hides its numbers.

     Scatter/bubble/map forms compare ALL pairs, not just neighbours — cap those
     at the first three slots and fold the rest into "Outros". */
