docs(readme): correct the feature list against the code

Every line under "See all features" was checked against source, not against the
docs. What was wrong:

- 20 languages. There are 23; ca, sv and vi were missing from the list
- 27 scopes in 13 groups. There are 29 in 14
- 150+ tools. There are 199, and 4 prompts rather than the 3 named
- GeoJSON import. No parser exists; places.service.ts takes gpx, kml and kmz
- default coordinates under Units. No setting by that name exists anywhere
- day check-ins under Collab. The fourth sub-feature is a What's Next list of
  upcoming activities; nothing checks anyone in or out of a day
- Apple as an OIDC provider. The discovery check requires a userinfo_endpoint,
  which Apple does not publish, and the callback is GET only. Also only one
  provider can be configured at a time
- role-based access. trip_members has no role column; access comes from an
  admin-set matrix over 16 trip actions
- one-time invite links. A trip link is one reusable rotating token with an
  optional expiry; the use limit belongs to the admin signup invites
- iOS-style bag distribution. It is a fill bar against an optional limit, and
  bag tracking is an instance switch that ships off
- fullscreen with a splash screen. The manifest says standalone, and there are
  no splash assets; only Android derives one from the icon
- the service worker caching the API. /api is NetworkOnly on purpose, because
  Workbox keys by URL and cannot vary on the session cookie
- Atlas streak tracking. It counts consecutive years travelled, not countries
- approved school holiday overlays. They come from openholidaysapi.org and are
  capped to 16 European countries
- 50 MB per file. Video goes to 500 MB

Missing outright: the plugin system, which the file did not mention once, sandbox
and SDK included. Also Collections and AI Parsing as addons, public share links,
guest members, the ICS feed, Transitous, Overpass, OSRM route profiles, GPX
export, place enrichment, the audit log, multi-leg flights, and the offline
machinery past "caches tiles".

The Addons box duplicated Costs and Packing, which are the same switches as the
core lines above it. It is gone, and the default state sits on the line instead,
which is what a self-hoster actually needs to know.

-#### 🧭 Trip planning
+#### 🧭 Planning
 
-- **Drag & drop planner** — organise places into day plans with reordering and cross-day moves
-- **Interactive map** — Leaflet or Mapbox GL with 3D buildings, terrain, photo markers, clustering, route visualization
-- **Place search** — Google Places (photos, ratings, hours) or OpenStreetMap (free, no API key)
-- **Place import** — shared Google Maps / Naver Maps lists, plus GPX and KML/KMZ/GeoJSON map files
-- **Day notes** — timestamped, icon-tagged notes with drag-and-drop reordering
-- **Route optimisation** — auto-sort places and export to Google Maps
-- **Weather forecasts** — 16-day via Open-Meteo (no key) + historical climate fallback
-- **Category filter** — show only matching pins on the map
+- **Day plans**: drag places between days and reorder inside a day, with undo. Notes and bookings drag the same way, and a map marker drops straight onto a day
+- **Maps**: Leaflet, Mapbox GL or MapLibre GL (OpenFreeMap, no token), with clustering, photo markers and route lines. 3D buildings and terrain are Mapbox only
+- **Place search**: Google Places when a key is set (photos, ratings, opening hours), otherwise OpenStreetMap with no key
+- **Place enrichment**: descriptions, facts, hours and photo candidates from OpenStreetMap, Wikipedia, Wikidata and Wikimedia Commons
+- **POI explore**: pull OpenStreetMap POIs by category for the current viewport over Overpass
+- **Import**: shared Google Maps and Naver Maps lists, plus GPX, KML and KMZ files
+- **Export**: GPX of a trip's places and tracks, and an ICS feed per trip or across all of them
+- **Routes**: auto-sort a day (nearest neighbour then 2-opt, locked stops and hotel anchors stay put), driving, walking or cycling profiles over OSRM, then open it in Google Maps or CoMaps
+- **Public transport**: door-to-door itineraries over Transitous
+- **Weather**: 16-day forecast from Open-Meteo, no key. Dates outside that window read the archive for the same date instead
+- **Day notes**: markdown body with an icon and a colour, reordered by drag and drop or moved to another day
+- **Trip dates**: move a trip and the days re-date themselves, either dragging the bookings along or re-anchoring them. Trips also copy and archive

-#### 🧳 Travel management
+#### 🧳 Bookings and money
 
-- **Reservations** — flights, accommodations, restaurants with status, confirmation numbers, files; import from booking confirmation emails and PDFs ([KDE Itinerary](https://invent.kde.org/pim/kitinerary))
-- **Costs** — track and split trip expenses (Splitwise-style): per-person / per-day breakdowns, settle-up, multi-currency
-- **Packing lists** — categories, templates, user assignment, progress tracking
-- **Bag tracking** — optional weight tracking with iOS-style distribution
-- **Document manager** — attach docs, tickets, PDFs to trips / places / reservations (≤ 50 MB each)
-- **PDF export** — full trip plan as PDF with cover page, images, notes
+- **Reservations**: 16 booking types with status, confirmation code, travellers and attached files
+- **Flights and trains**: several legs with stopovers, per-leg times and endpoint timezones, against 4,045 bundled airports so local times resolve without a key
+- **Accommodation**: a stay spans a range of days with a check-in window, and shows on every night it covers
+- **Booking import**: EML, PDF, PKPass, HTML and TXT confirmations through [KItinerary](https://invent.kde.org/pim/kitinerary). Needs the `kitinerary-extractor` binary, which ships in the Docker image
+- **AirTrail** (off by default): link a self-hosted AirTrail instance to import flights as reservations and keep them in sync
+- **Costs**: split expenses in integer cents with equal or custom shares, several payers per expense, settle-up suggestions, a settlement log, and CSV export
+- **Currencies**: a currency per expense with the rate frozen at entry. Rates come from Frankfurter, no key
+- **Packing lists**: categories, admin-managed templates, assignees, three visibility tiers, and a packed-of-total line. Bags with weight roll-up are a separate admin switch, off by default
+- **To-dos**: assignee, due date, priority, and a reminder before one falls due
+- **Files**: attach to a trip, place, day entry or reservation. 50 MB each, 500 MB for video, with trash and restore
+- **PDF export**: cover page, place photos, day notes, bookings and costs, with an optional page break per day

 #### 👥 Collaboration
 
-- **Real-time sync** — WebSocket. Changes appear instantly across all connected users
-- **Multi-user trips** — invite members with role-based access
-- **Invite links** — one-time or reusable links with expiry
-- **SSO (OIDC)** — Google, Apple, Authentik, Keycloak, or any OIDC provider
-- **2FA** — TOTP + backup codes
-- **Passkeys** — passwordless WebAuthn login (fingerprint / face / PIN / security key), admin-toggleable
-- **Collab suite** — group chat, shared notes, polls, day check-ins
+- **Real-time sync** (WebSocket): edits land live for everyone who has that trip open
+- **Members**: add by email or username, hand ownership to someone else, or add guests who have no login at all
+- **Permissions**: an admin maps each of 16 trip actions to admin, trip owner, trip member or everybody
+- **Invite links**: one reusable link per trip with an optional expiry. Admins can also issue signup invites with a use limit that drop the new account straight into a trip
+- **Public share**: a read-only trip page anyone can open without an account
+- **Collab**: group chat with replies, reactions and link previews, shared notes with attachments, polls, and a What's Next list of upcoming activities. Each of the four switches on its own
+
+#### 📔 Journal, Atlas and Vacay
+
+- **Journey** (off by default): dated entries with story, mood, weather and tags, photos and video from uploads or a linked [Immich](https://immich.app) or Synology Photos library, map views, co-authors, and a public share link
+- **Atlas**: mark countries and sub-national regions visited on [geoBoundaries](https://www.geoboundaries.org/) outlines, plus a bucket list, travel stats and a consecutive-years-travelled count
+- **Vacay**: leave calendar with half days, public holidays from date.nager.at, school holiday overlays for 16 European countries, carry-over between years, and joint or read-only sharing of a plan
+- **Collections** (off by default): a place library outside any trip, with labels, ratings, a custom image per place, copy-into-a-trip, and sharing by invite

-#### 📱 Mobile & PWA
+#### 🧩 Plugins
 
-- **Installable** — iOS and Android, straight from the browser, no App Store needed
-- **Offline support** — Service Worker caches tiles, API, uploads via Workbox
-- **Native feel** — fullscreen standalone, themed status bar, splash screen
-- **Touch optimised** — mobile-specific layouts with safe-area handling
+- **Third-party plugins**: install from the TREK registry or sideload a zip, switch on per instance, with their own pages under `/plugins/<id>`
+- **Sandboxed**: one child process per plugin, 63 grantable permissions, an admin-edited outbound host allowlist, memory and RPC caps, and daily caps on AI and notification calls
+- **Trust**: registry downloads are pinned by sha256 and checked against the author's minisign key. A sideloaded zip is marked unverified, and `TREK_PLUGINS_ENABLED=false` turns the whole system off
+- **Extension points**: map markers and layers, place details, day schedules, PDF sections, Atlas layers, journal rows, trip warnings, calendar sources, route profiles and notification channels. Plugin pages run in an opaque-origin iframe
+- **SDK**: [`trek-plugin-sdk`](https://www.npmjs.com/package/trek-plugin-sdk) on npm, with a manifest validator, a mock host, and a dev-link mode that runs a local build against real data
+
+#### 🤖 AI and MCP
+
+- **MCP server** (off by default): OAuth 2.1 with mandatory PKCE and dynamic client registration. 199 tools, 30 resources, 4 prompts
+- **Scopes**: 29 scopes in 14 groups, each one tickable on the consent screen. Tokens are bound to the `/mcp` resource, and every tool call lands in the audit log
+- **Reach**: create trips and days, edit places, packing lists, to-dos, costs, reservations, collections and journeys, mark countries visited, all inside the scopes the token holds
+- **Prompts**: `trip-summary`, plus `packing-list` and `budget-overview` when those addons are on
+- **Addon-aware**: seven addon gates decide which tools and resources a session sees. Flipping one drops live sessions so the surface re-registers
+- **Booking extraction** (off by default): read a confirmation with a local Ollama server, any OpenAI-compatible endpoint, or Anthropic, configured instance-wide or per user

-#### 🧩 Addons (admin-toggleable)
+#### 📱 Mobile and offline
 
-- **Lists** — packing lists + to-dos with templates, member assignments, optional bag tracking
-- **Costs** — expense tracker with splits and settle-up (who owes whom), multi-currency
-- **Documents** — file attachments on trips, places, and reservations
-- **Collab** — chat, notes, polls, day-by-day attendance
-- **Vacay** — personal vacation planner with calendar, 100+ country holidays, approved school holiday overlays, carry-over tracking
-- **Atlas** — world map of visited countries, bucket list, travel stats, streak tracking, liquid-glass UI
-- **Journey** — magazine-style travel journal with entries, photos (Immich/Synology), maps, moods
-- **AirTrail** — connect a self-hosted AirTrail instance to import and sync flights into reservations
-- **MCP** — expose TREK to AI assistants via OAuth 2.1
+- **Installable**: iOS and Android straight from the browser, no App Store. Runs standalone without browser chrome, with the status bar tinted per theme
+- **Phone layouts**: a separate shell below 768px with its own tokens, a bottom bar and safe-area insets. Which items sit in that bar is up to the user
+- **Offline reads**: the app shell and every route chunk are precached, and trips, places and file blobs live in a per-user IndexedDB store, so a trip opens with no network
+- **Offline writes**: mutations queue and replay with an `X-Idempotency-Key`, so a reconnect cannot double-apply. A stale edit is parked for a keep-mine or keep-theirs choice
+- **Offline maps**: pre-download a trip's raster tiles, and clear them again
+- **API responses are never cached** by the service worker. They vary per session, so they always come from the network

-#### ⚙️ Admin & customisation
-
-- **Dashboard views** — card grid or compact list · **Dark mode** — full theme with matching status bar
-- **20 languages** — EN, DE, ES, FR, IT, NL, HU, RU, ZH, ZH-TW, PL, CS, AR (RTL), BR, ID, TR, JA, KO, UK, GR
-- **Admin panel** — users, invites, packing templates, categories, addons, API keys, backups, GitHub history
-- **Notifications** — per-user preferences across email (SMTP), webhook, ntfy, and an in-app notification center
-- **Auto-backups** — scheduled with configurable retention · **Units** — °C/°F, 12h/24h, map tile sources, default coordinates
+- **Login methods**: password login, password registration, OIDC login, OIDC registration and passkey login each switch on and off on their own. `OIDC_ONLY` leaves SSO as the only way in
+- **SSO (OIDC)**: one provider by discovery, with PKCE and `id_token` verification (Authentik, Keycloak, Google and the like)
+- **2FA**: TOTP with ten single-use backup codes, and an admin can require it instance-wide
+- **Passkeys**: WebAuthn login by fingerprint, face, PIN or security key, off until an admin enables it. A passkey also satisfies the 2FA requirement
+- **Hardening**: per-IP limits on login, password reset and 2FA attempts, a password policy, secrets encrypted at rest and masked on read, and an SSRF guard on every URL you configure
+- **Admin panel**: users and invites, the permission matrix, packing templates, categories, addons, plugins, API keys, MCP tokens and OAuth sessions, backups, audit log, and GitHub releases
+- **Backups**: manual or scheduled hourly, daily, weekly or monthly, with retention in days. The zip carries the at-rest key, so a restore can decrypt its own secrets
+- **Notifications**: a per-user matrix of events against in-app, email (SMTP), webhook and ntfy, plus any channel a plugin registers
+- **Appearance**: light, dark or follow the OS, seven colour schemes plus a custom accent, transparency, compact density, reduce motion, and text size per tier
+- **23 languages**: en, de, es, fr, it, nl, hu, ru, zh, zh-TW, pl, cs, ar (right to left), br, id, tr, ja, ko, uk, gr, sv, vi, ca
+- **In-app help**: the wiki ships inside the image and is served from disk at `/help`, so the docs match the version you are running
