  /* LIGHT identity — LOCKED by Derek 2026-08-20: white field, blue wave,
     navy type, per his "VOICE INTELLIGENCE FOR BUSINESS" mockup. This
     supersedes the dark/mint palette from 2026-08-19 (which itself declared
     the light variant superseded — Derek ruled the other way; the layout and
     content of that pass are kept, only the palette reverts). --accent is
     the brand blue; --status stays a separate deeper hue for live/system
     indicators so it never reads as a second brand accent. */
