/* discover.css
   ============
   Discovery surface CHROME only: toolbars, ticker, section heads, the feed grid,
   the explore (list · preview · rail), collect/like affordances, the Drops bar,
   the Orbit greeting, the continue grid, and chips. Themed through tokens.css.

   AUTHORITY BOUNDARIES (this is why the cards stopped breaking):
     • PaQ card geometry/render  -> modules/paqcard/paqcard.css  (NOT here)
     • Hero layout/geometry      -> modules/paqhero/paqhero.css  (NOT here)
   This file must NEVER set width/height/aspect on `.paq-card`, and must never
   style `.disc-hero*`, `.disc-drophero*`, or `.disc-orbit-hero*`. The feed grid
   below positions cards at their intrinsic size; it does not resize them. */
