/*
  Common / shared styles — used by ALL themes.
  This file has NO colors or fonts hard-coded in it. Every color/font comes from
  CSS custom properties (--paper, --ink, --brass, --font-display, etc.) that each
  theme file (premier-blue.css, premier-red.css, vault-brass.css, ...) defines in
  its own :root block.

  Edit THIS file for any layout/structural change (spacing, grid, component
  markup styling) that should apply to every theme at once.
  Edit a theme-*.css file only when you want to change that theme's colors/fonts.

  This file must be loaded BEFORE the theme file in index.html, e.g.:

    <link rel="stylesheet" href="themes/common.css">
    <link rel="stylesheet" href="themes/premier-blue.css">

  Only the second <link>'s href needs to change to switch themes.
*/

  /* Structural design tokens shared by every theme — no colors/fonts here,
     just spacing/shadow/motion language so cards, buttons, etc. feel consistent
     regardless of which theme-*.css is loaded. */
