/* =========================================================================
 * Use-template modal — shared by /stage, /templates, and /stage/:id.
 *
 * Visual contract:
 *   • All surfaces & text use theme-aware tokens from variables.css so the
 *     modal renders identically in light + dark modes.
 *   • Footer CTAs reuse the canonical `.di-btn` family (designIdentity.css)
 *     instead of declaring private button styles, keeping it on-identity.
 *
 * Visibility: driven by the `hidden` attribute. Explicit
 * `[hidden] { display: none }` overrides exist because the modal host
 * uses `display: flex` for centering, which would otherwise win.
