/* ============================================================================
   EION frontend — app shell styling
   Aesthetic: honest "calm product UI" (ChatGPT-adjacent). Native CSS, no build.
   Theming: CSS custom properties swapped by [data-theme]. One theme locks at a
   time (Page Theme Lock). Three themes: light (milk white), dark, navy+gold.
   Shape rule: inputs 8px, panels/buttons 12px, big surfaces 18px, pills 999px.
   Motion: calm chrome; cinematic only inside the boot + Live/Jarvis moments.
   Zero em-dashes anywhere in visible copy.
