Add src/lib/components/ui/ContextMenu.svelte, replacing
TrackContextMenu and AlbumContextMenu (109 and 119 lines, 90%
identical): same positioning function (contextMenuPosition, exported
from the module, using MENU_WIDTH/SUBMENU_WIDTH moved to config.ts),
same backdrop, same Escape handling, same generic "Add to playlist"
submenu via {items, playlistAction, playlists}. Uses MenuItem for
actions (previously each reimplemented its own classes by hand) and
Artwork size="xs" for playlist thumbnails.
menus.svelte.ts (createTrackMenu) adapts to the new
contextMenuPosition; Home, Explore (track and album menus) and Mix
are migrated.
AccountMenu: panelClass (free-form Tailwind classes) becomes prop
width: 'sm'|'md'; adds Escape-to-close (accessibility improvement, it
didn't close before); TopBar and MobileHeader no longer wrap it in a
duplicate div.relative (its own root already is one). The panel's
z-index becomes z-(--z-menu), matching ContextMenu (previously z-20
in TopBar / no explicit z in MobileHeader).
Verified with npm run check/build; no authenticated visual QA (Docker
unavailable this session).
Add src/lib/actions/pressable.ts and clickOutside.ts (Svelte actions;
role/tabindex stay static in markup for SSR accessibility, the action
only adds click + Enter/Space) and src/lib/toggle.svelte.ts
(createToggle), used by playlists.svelte.ts and queuePanel.svelte.ts.
format.ts: adds plural(n, one, many); migrates the repo's 15 manual
pluralizations, unifying them to lowercase (visible diff in
Playlists, Home, liked, Explore).
player.svelte.ts: adds toQueueItem, isQueueCurrent, playAllOrToggle,
playShuffled; renames addToQueue -> playNextItem (the old name was
misleading: it inserts next, not at the end). Migrates the 5 places
that repeated the isCurrentQueue/playAll pattern (album, playlist,
liked, mix, Home). Simplifies liked.svelte.ts and recentlyPlayed.ts
with object spread instead of rebuilding every field by hand.
navigation.svelte.ts: adds searchHref (migrates the duplicated
buildHref from TopBar and Explore) and appNavLinks (added; its
adoption in Sidebar/TabsBar is left for a later pass, as noted
there).
menus.svelte.ts: createTrackMenu() replaces the manual context-menu
state (contextMenu + contextMenuStateFor + addToQueue) in Home,
Explore and Mix.
Deliberately left pending: removing tracks.ts's TrackTarget wrapper
and its 8 accessors is deferred — it's the riskiest change in the
plan, touches types across Home/Explore/Mix/menus, and couldn't be
visually verified without Docker this session.
Verified with npm run check/build.
