/* ---------------------------------------------------------------------------
 * Design tokens
 *
 * Three tiers, and feature CSS should only ever reach for the third:
 *
 *   Tier 0  channel tokens   raw R G B triples, so a colour can be reused at an
 *                            arbitrary alpha without hardcoding the channels at
 *                            the call site: rgb(var(--primary-rgb) / 0.15)
 *   Tier 1  primitives       the palette itself, named by hue + weight. These are
 *                            the values a theme swaps.
 *   Tier 2  semantics        what a colour *means* (danger, surface, overlay).
 *                            Feature CSS uses these so a palette change is a
 *                            one-line edit here rather than a sitewide sweep.
 *
 * Weights follow the Tailwind 50-900 scale. Intermediate steps (150, 610, 850…)
 * are strays inherited from other palettes — Material, iOS, Chakra, Bootstrap —
 * that arrived by copy-paste and sit a hair off the ramp. They are kept at their
 * exact original values so tokenizing changed nothing on screen; collapsing them
 * onto the nearest 100-step is a deliberate, visible follow-up, not this ticket.
