/* ============================================================================
   Utilitaria — styles
   Design language (see build brief §7–8):
     • Neutral ground: paper-white surfaces, near-black text, hairline borders.
     • The three STATUS COLOURS (green/amber/red) plus a quiet blue carry ALL
       meaning and are the only saturated colour anywhere.
     • One clean sans for UI; a monospaced face with tabular numerals for money,
       meter readings and account references — the ledger feel is the identity.
     • Sentence case; plain-verb buttons; visible keyboard focus; minimal motion.
     • Comfortable on a phone at 390px wide.
