/* ── DECAY SYSTEM — shared visual classes ────────────────────
   Architecture decision: Jin-ho + Marta + Tom (v67).
   Single definition. Used by: city-pulse.html, audit-trail.html,
   business-profile.html, and any future surface with decay bars.
   Per-page redefinition is a code smell — do not do it.

   Yuki: GPU-composited opacity and transform only.
         width changes on .decay-fill are acceptable here because
         the fill is a progress-bar child, not in a scroll container,
         and the transition is 400ms on initial render only.
         The rAF loop sets width directly (no CSS transition) for smooth animation.
   Hana: accent color — coral means "this is alive right now."
         As the bar drains, the tourist understands: this information is aging. */
