/* Lexpraxis buttons: Bootstrap 5.3 variants and variables, shared by app/public views.
 * Usage: class="btn awx-button btn-primary [btn-sm|btn-lg]".
 * Existing classes may remain as JS, positioning or state hooks. Only opted-in
 * buttons are normalized; tabs, editor tools and media controls are separate UI.
 * The scoped base also works on public pages that do not load Bootstrap.
 * Sizes: default 14px, btn-sm 12px, btn-lg 16px (at a 16px root size).
 * awx-button-icon makes an icon-only button square at the selected size.
 * awx-button-custom normalizes geometry only: pair with btn awx-button, without
 * a color variant, to preserve configured --awx-* gradients and inline colors.
