   Applications · Nibu M John — portal stylesheet
   --------------------------------------------------------------------------
   v3 — "Signal room" redesign.
   Same class contract as v2 (portal.js / components.js / icons.js are
   untouched and keep working): every selector, id-hook, and custom
   property name (--brand, --tint, --i, --bar, data-theme, aria-pressed,
   data-stuck…) is preserved. Everything visual is reimagined: a warm,
   near-black control-room base by default, lit by a three-colour signal
   ramp (acid lime / hot coral / warm gold) instead of the old violet
   aurora, with a cream "daylight" alternate for light mode. The suite
   index reads like an instrument panel — a live waveform, not a chart.
   No third-party fonts, no CDN, no build step — same zero-dependency
   rule as before.
