/* ==========================================================================
   SPLASH / LOADING — CELESTIAL ART-DECO TITLE CARD
   A nebula starfield, the ivory moon wordmark, a double-line frame with
   sparkle corners, and a PRESS START plate taken from the UI design sheet.
   The sacred-geometry loader (metatron + flower of life) is wired to the
   real boot progress (--p). Loads after premium.css, so these rules own
   the two screens.
