/* Components - buttons, icons, alerts, flash, dialogs, notifications. */

/* ========================================
   BUTTONS
    Single source of truth for all buttons.
    Variants: cta (accent), premium, secondary (neutral), good, bad,
    link (inline text-style).
   Modifiers: btn-block, btn-sm.
   Flat, uniform fill. Single frame mechanism: thick transparent
   inset lines on top (light) and bottom (dark), drawn over the
   background to give a 3D bevel. border: 0 removes the native
   button UA border so <a> and <button> render identically.
   Minimum height: every button, including btn-sm, must stay at or
   above --btn-min-height. Never add a modifier that pushes below it.
   The fill and bevel live on ::before so :active can scale only the
   look while the button box (and its click target) stays full size.
   The slot content is wrapped in .btn-inner so the label scales with
   the fill on press, keeping the press effect identical to before.
