   ── AUTHORING RULES ───────────────────────────────────────────
   · No raw colour values outside §01. Components consume tokens.
   · No @media blocks outside §16. Each breakpoint appears EXACTLY
     ONCE, ordered widest → narrowest. Max-width queries authored
     out of order silently override narrower breakpoints; that is
     what regressed five prior fixes in v2.0.
   · Animate only `opacity` and `transform`. Never `transition: all`.
   · `will-change` is applied transiently by class, never statically.
