/* READY LAUNCH MAIL CENTER. Layout after Cloud Residents (left menu, address card, stat tiles, mail rows with
   envelope thumbnails). LIGHT MODE (Joel, 2026-10-16) = Cloud Residents' warm paper palette (off-white #f6f5f1
   page, warm lines and greys) with Ready Launch's blue as the accent. DARK MODE = Ready Launch's portal tokens.
   The Dark mode row in the menu switches instantly, like Home Service Leads Fast. */
