A mode is a starting point, never a lock and never applied again on its own. modeStatus() (runtime)
compares the flags with the mode's preset: custom, what re-applying turns on and off, and which of
those the preset gained in an update since it was applied. mode_set keeps the preset of that moment
(modes.json "preset", flag names only, bounded; forgotten when the mode changes). Settings, the
first-run screen and the app menu's Mode row show Custom; Re-apply lists what it turns on and off
before it writes anything; a preset that grew is mentioned once on the mode row (Review), never applied.
Tests: exact match, changed by the owner, preset grew, choice made before the preset was kept.
Frame: AppMenu.tsx is a menu at the end of the titlebar cluster (before the caption buttons; macOS has none there). Its rows are `ShellSite.menu`: ordered groups of built-in rows by name and the app's own ({id, label, icon, shortcut, hint, when, checked, run | submenu}); `DEFAULT_MENU`, `menuWith` and `menuWithout` order, add and remove. A built-in row shows only when the app serves it (decks, `menu.languages`, themes, `menu.modes`, and `features`: zoom, store, workspaces, developer, updates), so no app gets a dead row. Language, Theme, Mode, Workspaces and Developer are submenus; Language and Theme apply live and keep the menu open, Mode asks the same keep-my-changes question as Settings (panel `menuModes()`). Keyboard: arrows, Home/End, type-ahead, the arrow along the reading direction opens a submenu, Esc closes one level; ARIA menu roles; submenus stay inside the window; one highlight for pointer and keys. It is an overlay like the other shell menus (the shell is raised, panes stay visible, nothing is dimmed).
Words: menuMessages.en.json (`wb.menu.*`), read through the framework i18n with that English as the fallback until the catalogs have them; words the panel already has are reused.
Host: `tab_zoom {id, factor}` (shell-only) sets a tab's page zoom with the engine's own zoom, clamped to 25%..500% and remembered per tab id in app data `zoom.json` (a number per tab id, nothing else; a closed tab's entry goes); without a factor it reads. A tab may forward four more shortcut names: `app-menu`, `zoom-in`, `zoom-out`, `zoom-reset`. The titlebar shows a zoom chip only while the pane in front is not at 100%.
create-waybetter: `tab_zoom` in the shell capability list; the template says which panel sections it lacks (store, updates) and how to add menu rows.
- PanelSite.features: the app's feature table; AreaPlugins draws one card per area (switch, count, grouped features, Settings button that runs the area's command in the site tab) and the core flags as Fixes
- a feature still backed by an old plugin file is switched through plugin_set_enabled from its card and left out of the JavaScript plugins list
- Modes: Onboarding (three cards, recommended preselected; an existing setup may be kept) and ModeSettings with the keep-my-changes question; openOnboardingWhenDue for ShellSite.start
- flags are saved sparsely (only what differs from the table's defaults)
- PanelSite.appearance.extra; palette commands of an area are listed under its name
- the kit's words for feature settings and health notes; English in the framework catalog
