/* Entry 006 — Inbox by emotional weight (rebuilt)
   Scene art direction: a real over-/under-water photograph — warm light at the
   surface falling to dark teal deep. Light messages float bright near the top;
   the one heavy message sinks into the dark, lit by a single warm glow that
   echoes the sunset above. One accent: that warm amber, the heavy message only.
   Crisper glass, fewer cards. Serif voice (Lora) for what actually matters. */
