/* =============================================================
   TempMail v5.0 — "Obsidian Signal"
   Author: Mehmet Kahya
   Created: 17 March 2024
   Last Updated: 27 October 2026

   Dark-first glass system: OLED black, electric-lime signal accent,
   violet ambient glow. Light mode swaps to warm paper + ink.
   Every container is a "double bezel": an outer tray + inner core.
