/*
 * ADDITIVE ONLY — this stylesheet never overrides a rule in app.css.
 *
 * The approved design system is complete for the screens the prototype built.
 * These rules supply the §28.6 components the prototype never needed, and the
 * §29.2 / §29.3 / §29.4 standards it was missing:
 *
 *   · the two animations referenced by loading and skeleton states
 *   · a visible focus ring on every interactive element (§29.3)
 *   · prefers-reduced-motion (§29.2)
 *   · pill, tabs, segmented control, toolbar, search, tooltip (§28.6)
 *   · the 620px and 1280px breakpoints (§29.4 — app.css has only 900px)
 *
 * Every value is drawn from the tokens already defined in app.css. No new
 * colour, type size or spacing value is introduced.
