Per Gemini's sharp note: rotating an intent's HUE toward the brand (harmonize)
erodes its meaning — a red stops reading as "error". What coheres a palette is
sharing the chroma + lightness PROFILE, not the hue. New temper(color, reference,
amount) keeps the hue and lerps L+C toward the reference. The demo's intent
cohesion switches harmonize -> temper, and the slider MOVES to the "Roles
canonicos" section (next to the intents, dynamic). Verified in-browser: threat hue
stays 358 (red) at 0% and 40% temper, only chroma/lightness shift; affirm stays
teal. harmonize stays in the engine for brand accents. RFC §6.2 updated.
