   Offex Audio — premium.css v3 "Warm Glass"
   Loaded LAST on every page (after styles.css and after each page's own
   <style> block), so it is the single source of truth for the look:
   warm cinematic bokeh background, floating glass pills, pill buttons,
   glass panels, tight elegant type.

   Visual layer only — no markup, text, SEO, tool ids or JS behaviour is
   changed by this file. Also loaded standalone by /app-ui.
