/* present.css: the presenter layer of Ocean of A Cnscsnss, Talk 1 (RUNTIME lane, 17 October 2026).
   Present mode, the 16:9 stage, the laser layer, blackout, the key chip, the presenter menu, the resume
   offer, the bed's one line and the pre-talk check. Classes only; present.js sets custom properties and
   transforms through the CSSOM, never a style attribute. Reads read.css tokens with fallbacks.
   Layers: chip / resume / bed line 800 · stage bars 900 · PRESENT tag 905 · check 960 · menu 970 ·
   toast 976 · laser 978 · blackout 980. */
