release: v0.18.0 (#725)

Release v0.18.0 — merges `dev` into `main`.

## Thanks

- [@lancetm714](https://github.com/lancetm714) for the accent-contrast
fix (#680 → #724).
- [@RichKidsDev](https://github.com/RichKidsDev) for reporting the
outdated Impressum (#697).

### Security

- **Journal drafts and password-protected entries no longer render
publicly
  as a subpage essay**
  ([#684](https://github.com/ralksta/immich-folio/pull/684),

[GHSA-987w-cpwm-c9g9](https://github.com/ralksta/immich-folio/security/advisories/GHSA-987w-cpwm-c9g9),
medium). A subpage's `essayFile` read the journal entry straight from
disk,
skipping the draft and password rules `/journal/<slug>` applies. It now
resolves through the same rules: a draft reads as missing for visitors,
and
  a protected entry shows its password gate, sharing the
  `lb_auth_journal_<slug>` cookie.

- **Immich descriptions are escaped in generated subpage essays**
  ([#684](https://github.com/ralksta/immich-folio/pull/684),

[GHSA-8ppx-39jv-q5xm](https://github.com/ralksta/immich-folio/security/advisories/GHSA-8ppx-39jv-q5xm),
  low). The essay built from a subpage's albums (`layout: essay` without
markdown) put each asset's Immich description into the page as raw HTML.
Captions are now HTML-escaped, and they go through `assetCaption()`, so
  `exif.caption: false` is respected there as well. Tracked in
  [#689](https://github.com/ralksta/immich-folio/issues/689).

- **Admin drafts no longer keep a typed password, and the contact form's
  email check runs in linear time**
([#727](https://github.com/ralksta/immich-folio/pull/727)). The admin's
  session drafts wrote a password as typed to `sessionStorage`; a draft
holding a plaintext password is now not kept (the unsaved-changes guard
still warns). The email pattern could backtrack polynomially on a
crafted
domain; its labels now exclude the dot and the length is checked first.
  Both found by CodeQL before release.

### Added

- **A built-in contact form with an inbox in the admin**
  ([#703](https://github.com/ralksta/immich-folio/pull/703), closes
[#702](https://github.com/ralksta/immich-folio/issues/702)). `/contact`
  needs neither SMTP nor a form service: each message is one file in
`content/messages/` (mode `0600`), read under the new _Messages_ tab,
where
_Reply by email_ opens the owner's mail client with the message quoted.
Messages older than `contact.retentionDays` (default 90) are deleted. An
optional ntfy push goes to `contact.notifyUrl` or `CONTACT_NOTIFY_URL`,
and
since [#709](https://github.com/ralksta/immich-folio/pull/709) it
carries a
  fixed "new message" line and nothing about the sender — no name, no
  address, no text. Spam is kept out without a captcha: an off-screen
honeypot, a minimum fill time, three submissions a minute per IP and a
cap
of 500 stored messages. With the Impressum on and no `legal.contactUrl`,
the Impressum links the form as its second contact channel. A new doctor
  check warns when the form is on but nobody is notified.

- **A privacy policy page, next to a list of what the site processes**
  ([#708](https://github.com/ralksta/immich-folio/pull/708)). `/privacy`
renders `content/privacy.md`, edited under Settings → Legal, and the
footer
links it once the file has text; `privacy.enabled: false` hides it.
Folio
writes no legal text. Beside the editor it lists what _this_
installation
  does, read off the configuration — the map, statistics, contact form,
password cookies, CDN — and marks every entry that involves a third
party.
_Insert headings_ adds the matching section headings and nothing else.
The
  doctor warns while the Impressum is on and there is no policy.

- **French, Spanish, Italian and Dutch interface translations**
([#681](https://github.com/ralksta/immich-folio/pull/681)), selected
with
  `settings.yaml: lang` as before. The admin panel stays English.

- **CDN mode for photos and videos**
([#681](https://github.com/ralksta/immich-folio/pull/681)). With
`CDN_URL`
set, image and video URLs point at a pull CDN whose origin is this
server,
  so repeat views reach neither the server nor Immich. A site password
switches the mode off, since a CDN would hand out cached photos without
  checking the unlock cookie. The CDN origin is added to the CSP, and a
  doctor check covers the password and `TRUSTED_PROXY_HOPS` cases. See
  `docs/deployment.md#cdn-mode`.

- **A reworked admin panel**
  ([#712](https://github.com/ralksta/immich-folio/pull/712),
  [#713](https://github.com/ralksta/immich-folio/pull/713),
  [#714](https://github.com/ralksta/immich-folio/pull/714),
  [#716](https://github.com/ralksta/immich-folio/pull/716),
  [#717](https://github.com/ralksta/immich-folio/pull/717),
  [#718](https://github.com/ralksta/immich-folio/pull/718),
  [#719](https://github.com/ralksta/immich-folio/pull/719),
  [#721](https://github.com/ralksta/immich-folio/pull/721)):
- **A sidebar instead of the header row**, grouped by task, with an
unread
    count on Messages and a dot on Diagnostics while Immich is down. It
    collapses to an icon rail, with names shown on hover and focus, and
    remembers that per browser.
  - **`/admin` is an overview**: what needs attention (unread messages,
    doctor warnings), published pages, journal entries and recent views.
  - **The site's own visual language** — the preset's fonts, hairline
borders, the square marker — and one page header on every screen. The
accent is kept for the current place and the primary action; switches
    are now pills reading ON or OFF, in green rather than the accent, so
    Studio Modern's red no longer makes an enabled setting look like an
    error.
- **The page builder is a structure list and a panel.** Hero, subpages
and
standalone albums sit in one list on the left, subpages drag-sorted in
    place; the selected entry is edited on the right instead of in an
    overlay.
- **Dialogs only where a change is permanent.** Deleting a message or a
journal entry, and resetting the favicon (which used to delete the file
without asking), go through one confirm dialog in the admin's own look.
Removals in the page builder, which only touch unsaved state, happen at
    once and offer _Undo_. No `window.confirm()` is left.
  - **Feature switches are grouped by meaning** as one-line rows under
Settings → General; page transitions and scroll-to-top moved to Theme →
    Look & motion. No setting keys changed.

### Changed

- **Fonts and the Leaflet stylesheet are served from the site itself**
([#700](https://github.com/ralksta/immich-folio/pull/700)). Every page
used
to link `fonts.googleapis.com`, which sends each visitor's IP address to
Google. The server now fetches a theme's Google fonts once, rewrites the
  stylesheet and caches the files in `content/.fonts/`; custom fonts in
`theme.fonts` keep working. If Google cannot be reached before a font is
  cached, the page falls back to the theme's system fonts. `leaflet.css`
  comes from the npm package instead of unpkg. The CSP drops
  `fonts.googleapis.com`, `fonts.gstatic.com` and `unpkg.com`.

- **Email addresses are kept out of the served HTML**
([#705](https://github.com/ralksta/immich-folio/pull/705)). The
Impressum
and footer render the address only after hydration, from an encoded
form,
  so harvesters reading raw HTML find nothing. Without JavaScript the
Impressum shows `name [at] example [dot] de`. This defeats bulk
harvesting,
  not a person with a browser.

- **The Impressum cites § 5 DDG and links its contacts**
  ([#698](https://github.com/ralksta/immich-folio/pull/698), reported in
  [#697](https://github.com/ralksta/immich-folio/issues/697) by
[@RichKidsDev](https://github.com/RichKidsDev)). The TMG was replaced by
the
DDG in May 2024; `legal.heading` replaces the line for other laws (e.g.
  § 5 ECG in Austria). `legal.contactUrl` and `legal.contactLabel` add a
  contact form as the second channel, so a phone number stays optional.
  Email, phone and contact URL are now links, and the "Created with the
Impressum generator by eRecht24" line, shown on every site whether true
or
not, is gone. Settings → Legal gains fields for heading, contact URL,
VAT
  ID and tax number, and a doctor check flags missing details.

- **Missing pages answer `404`**
([#704](https://github.com/ralksta/immich-folio/pull/704)). Every
missing
  page used to answer `200`, because streaming had started before
`notFound()` ran. `/contact`, `/impressum`, `/map` and `/privacy` while
switched off, and `/journal/<slug>` without an entry, now return a real
404 with the same not-found page. Album and subpage slugs still depend
on
  Immich and stay soft 404s.

- **Passwords set in the admin are stored as scrypt hashes**
  ([#706](https://github.com/ralksta/immich-folio/pull/706), closes
  [#690](https://github.com/ralksta/immich-folio/issues/690)). Subpage,
album, journal-entry and site passwords were written as typed. The save
routes now hash them; a stored hash reads _Protected_ with _Change_ and
_Remove_ and is never put into an input. Visitors who unlocked a page
stay
signed in across unrelated saves. Existing plaintext passwords are
hashed
  the next time their file is saved in the admin.

- **One notification surface in the admin**
([#707](https://github.com/ralksta/immich-folio/pull/707)) replaces
every
`alert()`: errors stay until dismissed, successes clear themselves, and
  screen readers announce both.

### Fixed

- **Map tiles load again**
([#701](https://github.com/ralksta/immich-folio/pull/701)). CARTO
started
answering every tile with an "API KEY REQUIRED" image, leaving `/map`
and
journal map blocks as a grey grid. Tiles now come from OpenStreetMap;
the
  dark look is a CSS filter, so the map now follows the colour mode.

- **The page builder no longer drops a subpage's `proofing:` flag on
save**
([#711](https://github.com/ralksta/immich-folio/pull/711)). A page
switched
  off for proofing by hand reverted after any unrelated edit.

- **Unsaved edits in Settings and About survive switching admin tabs,
and a
  backup restore is no longer overwritten by the next save**
([#687](https://github.com/ralksta/immich-folio/pull/687)). Editors that
were open during a restore now reload and offer unsaved edits back as a
  conflict. Also: "Restore my changes" after a conflict found nothing,
removing an album left its drawer showing the next album, and the
journal
  saved (rotating a backup) without changes.

- **Accent-backed buttons stay readable with a light or malformed
accent**
  ([#724](https://github.com/ralksta/immich-folio/pull/724), supersedes
[#680](https://github.com/ralksta/immich-folio/pull/680)) — contributed
by
  [@lancetm714](https://github.com/lancetm714). A white accent made the
  proofing dialog's _Download selected (.zip)_ button white on white.
`theme.accent` is now accepted as hex only and normalised to `#rrggbb`,
anything else falls back to the preset, and the proofing dialog and
filter
  pills use the mode-aware `--on-accent` text colour from #688.

- **Every preset's accent is visible in both colour modes**
([#688](https://github.com/ralksta/immich-folio/pull/688)). Presets had
one
accent for both modes; minimal's dark mode drew black buttons on black.
  Presets now carry a light and a dark accent, and text on accent-filled
  buttons picks black or white for contrast. A custom accent stays the
  owner's choice in both modes.

- **Visitor-side inconsistencies**
([#685](https://github.com/ralksta/immich-folio/pull/685)): after
visiting
`/impressum`, every subpage header turned centred and uppercase; back
links
  announced "Back to Back to …"; the hero EXIF chip ignored
`exif.location`/`camera`/`settings`; videos in journal entries opened as
  stills; the setup screen named a non-existent `.env.example`.

- **An essay's lightbox walks only the photos the story shows**
([#686](https://github.com/ralksta/immich-folio/pull/686)), not every
photo
of the subpage's albums, and the proofing bar in essays shows the
selection
  count instead of a filter button that did nothing.

- **The page panel scrolls with the mouse wheel**
  ([#720](https://github.com/ralksta/immich-folio/pull/720)).

- **The journal editor's top bar wraps on phones**
  ([#723](https://github.com/ralksta/immich-folio/pull/723), closes
[#675](https://github.com/ralksta/immich-folio/issues/675)), so the
title
  stays editable and Save stays on screen.

- **Every admin form field has a name for assistive technology**
([#715](https://github.com/ralksta/immich-folio/pull/715)). Only two
inputs
had a linked label; 47 are linked now, and clicking a label focuses its
  field.

### Internal

- **`SettingsEditor` and `PageBuilder` are split up**
  ([#710](https://github.com/ralksta/immich-folio/pull/710),
[#711](https://github.com/ralksta/immich-folio/pull/711)). The
2,200-line
settings editor is a shell with one file per section; the page builder's
YAML handling and edits are pure functions under test. Both were checked
  side by side against `dev` for identical output.
- **`useAdminFetch()`**
([#707](https://github.com/ralksta/immich-folio/pull/707))
gives Analytics, Messages, Backups and the journal list one loading and
  error pattern.
- README brought up to v0.17.0
  ([#678](https://github.com/ralksta/immich-folio/pull/678),
  [#679](https://github.com/ralksta/immich-folio/pull/679)).

### Upgrade notes

**`content/` gains two directories the app writes to:**
`content/.fonts/`
for the cached fonts and `content/messages/` for contact-form messages.
Both
are created on demand, so a writable `content/` is enough, as before.

**The server needs outbound HTTPS to Google once per font** to fill the
font
cache. Until then pages fall back to the theme's system fonts. Visitors'
browsers no longer contact Google.

**A custom CSP or reverse-proxy allowlist** must now allow
`tile.openstreetmap.org` for images instead of
`*.basemaps.cartocdn.com`,
and no longer needs `fonts.googleapis.com`, `fonts.gstatic.com` or
`unpkg.com`. The built-in CSP is updated.

**`theme.accent` must be hex** (`#rgb`, `#rrggbb` or `#rrggbbaa`).
Anything
else, including a value without `#`, falls back to the preset's accent.

**Plaintext passwords in `gallery.yaml`, `settings.yaml` or journal
entries**
are hashed the next time that file is saved in the admin; one save
clears the
doctor's warning.

**New, optional settings:** `contact.*` (the form is off by default),
`privacy.enabled`, `legal.heading`, `legal.contactUrl`,
`legal.contactLabel`,
and the `CDN_URL` and `CONTACT_NOTIFY_URL` environment variables. See
`content/settings.yaml.example` and `.env.local.example`. In the example
file,
`vatId` and `taxId` had swapped sample values; check yours if you copied
them.

No `IMAGE_CACHE_VERSION` bump is needed this time.
