pleNx v0.1.0

First release of pleNx, a third-party native Plex
client for Nintendo Switch, macOS, Windows, Linux, Android, PS4 and PS Vita.

pleNx is a fork of Switchfin
(a Jellyfin client) fully migrated to the Plex API, with a complete UI overhaul.

Features

• [breaking] Full migration from the Jellyfin API to the Plex API
  (Switchfin → pleNx): sign-in via the plex.tv PIN flow (link code), server
  discovery and connection selection, libraries, home hub, movies, shows,
  collections, search, and playback (direct play and transcode) backed by mpv
• Complete UI overhaul with the new pleNx branding: icon-only sidebar,
  full-bleed detail pages (backdrop banner with title logo, inline action
  buttons, director-first cast row), fully scrollable season / playlist /
  collection views, redesigned search (fixed keyboard, history, suggestions),
  quick-actions side panel on any poster (X or long-press),
  guaranteed 2:3 poster ratios, structured skeletons and empty states,
  pill-shaped toasts, focus halo clipped to its scroll frame
• Plex Watchlist: dedicated sidebar tab with provider-backed sorting and
  filters (movies/shows, on-server availability — off-server posters are
  dimmed), add/remove from detail pages and the quick-actions menu
• Offline downloads: storage gauge, active/completed sections, one-tap
  season or whole-show download, local playback
• Remote file servers managed from the UI: add/edit/delete WebDAV, FTP,
  SFTP and HTTP(S) shares with a mandatory connection test before saving
• Genre cards illustrated with the Kometa default
  posters (proxied and resized by the Plex server, nothing bundled)
• Playlists (custom posters honored, square cards), collection pages with
  item-count headers, "see all" card opening full hub pages, person pages,
  "Play again" on fully-watched shows, connection loading screen with async
  server probing (no more frozen first frame)
• Available in 14 languages
• Nintendo Switch specifics: working applet-mode warning screen with HOME
  tile (forwarder) installation flow, system Standard font by default
  (consistent accented glyph spacing), USB drives via libusbhsfs

Fixes

• Infinite relayout loop on fractional layout widths that emptied grids,
  killed controller navigation and crashed the app on both desktop and Switch
• Ghost focus on recycled or detached views: the focus memory is now
  validated and purged in the borealis layer (focus could previously land on
  invisible cells, e.g. when returning from the sidebar)
• Empty-text yoga measurements returning NaN (seasons without a summary
  rendered a full-screen header and zero episodes)
• All vertical views now use "centered" scrolling: the previous "natural"
  mode could trap or steal the controller focus at scroll edges
• Borealis framework fixes shipped as a patch applied on top of the submodule
  (focus guards, keyboard sticky keys, click animation overshoot, concentric
  highlight, Switch shared-font order, notification restyle)

Build

• Local Nintendo Switch build via Docker (scripts/build-switch.sh,
  devkitPro image, deko3d driver by default, builtin NSP forwarder)
• Continuous delivery via GitHub Actions: pushing a v* tag builds all
  platforms (Switch NRO, macOS DMG, Windows, Linux Flatpak/Arch, Android APK,
  PS4 PKG, PS Vita VPK) and drafts a GitHub release with notes taken from this
  changelog — the borealis patch is applied in every CI job, and the in-app
  update checker performs a real semantic version comparison
