/* ==========================================================================
   MailPro Design System
   Palette: deep indigo (--ink) for structure/headings, warm coral (--accent)
   for actions — chosen to feel like "mail in motion" (warm) against a calm,
   trustworthy structural color (cool indigo), on a quiet neutral background.
   Type: Space Grotesk for headings/numbers (distinctive, confident numerals
   for stat cards), Inter for body/UI (built for dense, legible data screens).
