/**
 * OpenStation — My WordPress: server-side preview-action descriptors.
 *
 * Plugins register action buttons that appear in the right-pane of
 * any My WordPress section (posts, pages, users, media, plugin-
 * defined kinds). Server-side declaration buys:
 *
 *   - Capability gating: an action a viewer can't run is never
 *     shipped to their bundle (no client-side hide-after-render
 *     race).
 *   - Optional script enqueue: the registering plugin can declare a
 *     `script` handle and we'll auto-enqueue it for users who can
 *     see the action.
 *   - One source of truth for both the right-pane action row and
 *     the per-tile context menu — same descriptor.
 *
 * Descriptor shape:
 *
 *   [
 *     'id'         => 'my-plugin/compress-image',  // required, unique
 *     'label'      => 'Compress this image',       // required
 *     'icon'       => 'dashicons-image-rotate',    // optional
 *     'capability' => 'upload_files',              // optional, default 'read'
 *     'mime'       => '^image/',                   // optional, PCRE
 *     'sections'   => array( 'media' ),            // optional, default all
 *     'script'     => 'my-plugin-actions',         // optional handle
 *   ]
 *
 * `sections` entries match a section's **id** (`'media'`,
 * `'cpt-atf-forms'` — auto-registered CPT sections are prefixed
 * `cpt-`), a section's declared **post type slug** (`'atf-forms'`),
 * or `'*'` for every section. Matching happens client-side.
 *
 * Timing: descriptors are re-collected when the window config is
 * serialized for the browser (see
 * `openstation_my_wordpress_refresh_window_config()`), the same late
 * pass that enqueues declared `script` handles — registering the
 * filter any time during a normal bootstrap is fine.
 *
 * @package OpenStation
 */
