/* ══════════════════════════════════════════════════════════════════════════
   PROMPT OPTIMIZER — "LAGOON & EMBER"
   Design system + application shell.

   House rules (enforced throughout):
   · No Inter, no Arial, no system-font fallback as the primary voice.
   · No pure #000 and no untinted grey — every neutral carries a teal or
     warm cast so the surface has a temperature.
   · No purple→blue gradient. Accent is ember orange against lagoon ink.
   · No cards nested inside cards. Depth comes from rules, spacing and
     a single elevation step.
   · No bounce / elastic easing. Motion is ease-out and short.
