/* =================================================================
   components.css — canonical component library.

   Built on design tokens from input.css (:root). Every reusable UI
   primitive lives here so pages compose from a single language.

   Load order on every page:
     1. style.css            (legacy page-specific rules)
     2. components.css       (this file, design system primitives)
     3. tailwind.css         (Tailwind utilities layered on top)

   Newer pages should prefer .surface / .btn / .input primitives over
   legacy classes. The legacy classes still work and can co-exist.
   ================================================================= */


/* =========== Element resets ============================
   Tailwind's preflight is disabled (see tailwind.config.js), so the browser
   default button chrome — light grey/white background, 1px outset border,
   system font — leaks through on every <button> that doesn't explicitly set
   its own background. Rather than sprinkle `bg-transparent` across every
   call site, normalize here. Named classes (.btn, .btn-logout, .notif-bell,
   .login-btn, etc.) override by higher specificity. */
