   CML Dashboard — Polish Layer
   ----------------------------------------------------------------
   Loaded AFTER /mobile.css. Adds restrained glass-morphism,
   material depth, and reveal animations. UI polish only —
   no layout, no business logic, no data shape changes.

   Cascade order:
     1. inline page <style>     — base layout + tokens
     2. /mobile.css             — phone + tablet overrides
     3. /polish.css (this file) — universal aesthetic polish

   Class prefixes:
     .pr-*    polish-specific utilities
     .js-*    state classes added by polish.js on load
