   PHYSEA COMPONENT LIBRARY  ·  physea-components.css
   The shared, reusable component kit. Link it AFTER the palette + skin:

     <link rel="stylesheet" href=".../physea-tokens.css">   (palette — required)
     <link rel="stylesheet" href=".../physea-skin.css">     (cursor/scrollbar/.skin-card — required)
     <link rel="stylesheet" href=".../physea-components.css"><!-- this file -->

   Everything here references design-system tokens (var(--paper), --ink,
   --primary, --rule, --font-*, --button-radius, --radius-*) so a palette edit
   in physea-tokens.css re-skins all of it — light AND dark — for free.
   Photoreal language (raised clay, layered shadows, surface gradients, glass).
   Cascade order matters: tokens → skin → components → any page-inline overrides.
