468 *
469 * @param array $config {
470 * Desktop shell configuration.
471 *
472 * @type string $currentPage The current admin page URL.
473 * @type string $currentTitle The current page title.
474 * @type string $currentIcon Dashicon class for the current page.
475 * @type string $adminUrl The base admin URL.
476 * @type string $colorScheme The active admin color scheme.
477 * @type array $dockItems Dock items derived from the admin menu. Core WordPress pages (Dashboard, Posts, Plugins, Users, Settings, CPTs…) are ordered first; plugin-contributed top-level routes (admin.php?page=*) follow. Items hidden via `openstation_dock_placement` are omitted.
478 * @type array $nativeWindows Server-declared native windows (via `openstation_register_window`). Shell registers + syncs tiles based on this list — activation/deactivation is a diff without shell reload.
479 * @type array $serverWidgets Server-declared right-column widgets (via `openstation_register_widget`). Shell syncs the widget registry + dynamically loads plugin scripts so widgets appear in the picker without a shell reload.
480 * @type array $serverWallpapers Server-declared wallpapers (via `openstation_register_wallpaper`). Same lifecycle — shell loads the plugin's JS, reads the full `WallpaperDef` from `window.openStationWallpapers[id]`, and registers / unregisters as plugins activate / deactivate.
481 * @type array $serverCommandScripts Script handles opted-in via `openstation_register_command_script`. Shell injects each URL on activation so commands registered by `wp.os.registerCommand` appear in the palette live. Deactivation unregisters any commands whose `owner` matches the departing handle.
482 * @type array $serverCommands Server-declared command metadata (via `openstation_register_command`). Advisory today — reserved for future pre-registration shims.
483 * @type array $serverSettingsTabScripts Script handles opted-in via `openstation_register_settings_tab_script`. Shell injects each URL on activation so tabs registered by `wp.os.registerSettingsTab` appear in the OS Settings window live. Deactivation unregisters tabs attributable to the departing handle.
484 * @type array $serverSettingsTabs Server-declared settings-tab metadata (via `openstation_register_settings_tab`). Enables live unregistration on plugin deactivation without requiring JS to set `owner`.
485 * @type array $desktopIcons Server-declared desktop icons (via `openstation_register_icon`). Rendered on the wallpaper as clickable shortcut tiles.
486 * @type array $accentColors Swatch list for the OS Settings accent picker. Filterable via `openstation_accent_colors`.
487 * @type array $toastTypes Toast-notification type map. Filterable via `openstation_toast_types`.
488 * @type string $defaultWallpaper Wallpaper slug applied on first boot. Filterable via `openstation_default_wallpaper`.
489 * @type array $session Saved session (windows, focused, updated).
490 * @type string $sessionUrl REST endpoint for saving the session.
491 * @type string $mediaUrl REST endpoint for media uploads (wp/v2/media).
492 * @type string $restUrl REST API root from rest_url(), safe for pretty and plain permalink installs.
493 * @type string $defaultWindowUrl REST endpoint for saving the default-window preference.
494 * @type array $defaultWindow { enabled: bool, url: string } — current default-window preference.
495 * @type bool $canUpload Whether the user holds the `upload_files` capability.
496 * @type string $pluginUrl Plugin base URL (no trailing slash). Used by the shell to locate vendor assets and by plugins to build asset URLs.
497 * @type string $pluginVersion Plugin semver string. Surfaced in the OS Settings → About tab; plugins can read it to gate features by version.
498 * @type string $aboutFeedUrl Authenticated admin-AJAX URL that returns the cached OpenStation journal feed for the About tab.
499 * @type string $restNonce Nonce for the session REST endpoint.
500 * @type string $soloWindow Window id when the shell was asked to paint exactly one window (`?openstation_solo=<id>`); '' otherwise. No dock, taskbar, wallpaper or desk, and no session restore.
501 * @type string $portalUrl Canonical `/openstation/` URL.
502 * @type bool $fromPortal Whether the shell was reached via the portal.
503 * @type bool $fromPortalIntent Whether the portal redirect resolved from an explicit `?target=…` (user navigation intent) rather than the session's focused window or the default-window fallback. Distinguishes a bare `/openstation/` visit from a portal-redirected admin-bar click so the shell can honour the URL the user actually asked for.
504 * @type array $seenIntros Slugs of one-time announcements the user has dismissed (e.g. `['openstation-rebrand']`).
505 * @type string $seenIntrosUrl REST endpoint for the seen-intros surface — POST `/seen` to mark, DELETE the base to reset.
506 * @type bool $rebrandNotice Whether to offer this user the one-off announcement explaining the rename from Desktop Mode to OpenStation. True only when migration 5 flagged this user as a Desktop Mode user from before the rename AND they haven't dismissed the `openstation-rebrand` intro. Only ever present in the shell config, so the announcement never reaches the classic admin.

854 * dependency chain — the Gutenberg runtime, ~800 KB gzipped — on
855 * every admin page. On a SHELL page that is pure dead weight: the
856 * shell suppresses Core's palette unconditionally (the ⌘K keystroke
857 * and the admin-bar icon both route to the shell's own palette), so
858 * the runtime it powers can never be shown. Unhooking here lets the
859 * deferred manifest (`openstation_build_command_palette_assets_payload()`)
860 * capture the chain instead, and the shell loads it on the first
861 * palette invocation.
862 *
863 * Deliberately scoped: classic-mode requests keep Core's default,
864 * because a classic page is Core's own UI where Core's palette is the
865 * right one.
866 *
867 * Windows are handled separately by
868 * {@see openstation_chromeless_should_trim_command_palette()} in
869 * `includes/render/chromeless-trim.php` — same idea, but it has to
870 * drop the whole palette *family* rather than just unhook Core's
871 * callback, and it exempts block-editor screens. Unhooking alone is
872 * not enough there: a third-party palette extension that declares
873 * `wp-commands` keeps the entire chain queued as its dependency.
874 *
875 * Priority 0, ahead of Core's default 10, so the removal lands
876 * before the callback fires. On WP 6.9 (function exists, no default
877 * hook) the `remove_action()` is a harmless no-op.

887 /**
888 * Emits `<link rel="preload">` hints for the shell's critical-path
889 * assets so the browser starts fetching them as soon as it parses
890 * the document `<head>`.
891 *
892 * Without this, the browser doesn't discover the main `desktop.min.js`
893 * bundle URL until it parses the footer `<script>` tag — typically
894 * ~1 RTT after the rest of the page has started loading. For a 464 KB
895 * bundle on a midrange phone that's a measurable FCP delay; on a
896 * slow connection it dominates first paint entirely.
897 *
898 * Hooked at `admin_print_styles @ 1` so the preload tags land in
899 * `<head>` BEFORE the regular `<link rel="stylesheet">` tags (which
900 * default to priority 10) and well before the footer `<script>`
901 * tag. The `wp_resource_hints` filter is frontend-only (`wp_head`-
902 * driven) and isn't invoked in admin context, so we emit our own
903 * tags.
904 *
905 * Four targets by default, split across two relationship types:
906 * - `desktop[.min].js` (preload) — the shell bundle (biggest win),
907 * consumed by the footer `<script>` on this very load.
908 * - `desktop.css` (preload) — shell base CSS, needed for first
909 * paint. Its registered handle is `filemtime`-stamped so the
910 * stylesheet URL matches this hint exactly (a `?ver=` mismatch makes
911 * the browser treat the preload as unused).
912 * - `window-system[.min].js` (prefetch) — lazy bundle `<script>`-
913 * injected by the main bundle on the first `open()`.
914 * - `shell-overlays[.min].js` (prefetch) — lazy bundle injected on the
915 * first toast / dialog / context-menu.
916 *
917 * The lazy bundles use `prefetch` rather than `preload`: they're loaded
918 * later (often beyond the ~3s window Chrome allows a `preload` before it
919 * warns "preloaded but not used in time"), so `prefetch` keeps the early
920 * low-priority cache fill without the must-use-now contract.
921 *
922 * Plugins can extend the hint list via the `openstation_preload_hints`
923 * filter — e.g. a settings tab whose bundle the user opens on every
924 * visit can opt its own URL into the preload phase.
925 *
926 * Same-origin resources only — no `crossorigin` attribute. CDN hosts
927 * that serve `wp-content/plugins/` from a different origin should
928 * supply absolute URLs through the filter; in that case the consumer
929 * is responsible for the `crossorigin` semantics.
