Merge branch 'claude/relaxed-faraday-h4zd09' of https://github.com/pablovolenski/vienalatina

Decap looks like a different product because it cannot be made to look like
this one: its maintainer's answer is override the CSS and accept that class
names move between releases, or fork it and carry that forever. Neither is
worth building on, so editing moves into the app that already has the site's
design and this project's tests.

Posts are files in git, so the editor is a form that commits a file through
Gitea's contents API. No working copy, no queue, no new state, and no way for
the pipeline to tell which editor wrote the file — which is what makes running
both at once safe. Decap keeps working; nothing here removes it, and the
fallback if something is missing is switching tabs.

Filenames and frontmatter are not this module's to invent. They are the
contract scripts/translate.py reads: `<basename>.es.md` is what split_lang()
parses, the date prefix is what keeps two posts with one title off a single
URL, and the absence of `translated_from` is what marks a file as something a
person wrote. Several tests import translate.py and run its own parser over
what the editor produced, because a file it cannot parse publishes in Spanish
and is never translated, with nothing reported anywhere.

Commits carry the writer's own Gitea account rather than a bot's, so history
says who wrote each post and Gitea's permissions apply unchanged. That needs
their access token, which lives in the database and never in a cookie: Flask
signs cookies but does not encrypt them, and a token is enough to commit as its
owner. Gitea expires tokens after about an hour, so they refresh ahead of
expiry and retry once on rejection — without that, saving would start failing
partway through an afternoon for no reason the writer could see.

Publishing is admin-only. Posting to the internal board and publishing to the
public site are different permissions, and the second is the larger grant.

Listing caches frontmatter against the git blob sha, because the contents API
returns names without bodies: that turns one request per post on every page
load into one request in total, and needs no invalidation, since a sha changes
only when the file does.

Verified: 97 checks. The filename translate.py parses, an authored source that
is_generated() rejects, the freeze toggle round-tripping, a stale sha refused
with the other edit intact, six filename shapes that must 404 including a
generated sibling, plain members refused, an SVG rejected as an image, uploads
not colliding, the cache reading each file once and refreshing when it changes,
and a preview that renders markdown, escapes script tags and publishes nothing.
Smoke-tested live: routes register and gate correctly.

+file through Gitea's contents API, so Woodpecker sees an ordinary push and
+translate → build → deploy runs unchanged. Commits carry the author's own

+
+It exists because Decap has no supported way to be themed — its maintainer's
+answer is override its CSS and accept that class names move, or fork it — so
+`/admin/` would always look like a different product bolted on.
+
+**Decap is still running.** Both editors write the same files, and the pipeline
+cannot tell them apart, so there is no cutover to get wrong. `docs/server-setup.md`
+§11.8 covers removing Decap when the new editor has earned it.
+
+Filenames are the contract, not a detail: `YYYY-MM-DD-slug.es.md` is what
+`split_lang()` parses and what keeps two posts off one URL. The tests import
+`scripts/translate.py` and run its parser over what the editor writes, because
+a file it cannot parse publishes in Spanish and is never translated, silently.

 - **Retention:** soft-deleted posts stay in the database until removed by hand.
   If you want a real retention limit, that is a `DELETE ... WHERE deleted_at <`
   in this same cron slot — and a decision to take deliberately, not by default.
+
+### 11.8 The content editor (`/comunidad/contenido/`)
+
+Admins and the owner can write, edit and delete posts and pages from inside the
+members area, instead of Decap at `/admin/`.
+
+**Decap is still there and still works.** Nothing was removed. Use the new
+editor for a few real posts first; if something turns out to be missing, switch
+tabs. Removing Decap is a separate decision — see below.
+
+Nothing extra to install or configure: it runs in the container already serving
+`/comunidad/`, and commits through the Gitea OAuth application registered in
+§11.1. Two settings exist if the repository is ever renamed:
+
+```
+CONTENT_REPO=pablo/vienalatina      # owner/repo inside Gitea
+CONTENT_BRANCH=main
+```
+
+**How publishing works.** The editor is a form that commits a file through
+Gitea's contents API. Gitea's webhook fires Woodpecker, and translate → build →
+deploy runs exactly as it does for a Decap commit — the pipeline cannot tell
+which editor wrote the file, which is what makes running both at once safe.
+
+**Commits are made with your own account**, not a bot's, so `git log` shows who
+wrote each post and Gitea's permissions apply unchanged. Your access token is
+stored in the members-area database (never in a cookie) and refreshed
+automatically; Gitea expires them after about an hour, and without refreshing,
+saving would start failing mid-afternoon for no visible reason.
+
+**Filenames follow the same rules Decap used**, because `scripts/translate.py`
+reads them: `YYYY-MM-DD-slug.es.md` for posts, `slug.es.md` for pages. A file
+whose name breaks that contract publishes in Spanish and is never translated,
+with nothing reported anywhere — which is why the tests import translate.py and
+run its parser over what the editor writes.
+
+**Two people editing one post** is a visible conflict, not a silent overwrite:
+the form carries the file's git sha and Gitea rejects a write whose sha has
+moved on. You are asked to reopen the post rather than losing the other edit.
+
+**Images** are committed as a second, separate commit before the post itself,
+so publishing with a picture produces two pipeline runs. Harmless, and the
+alternative — batching both into one commit via the git trees API — is
+considerably more code for something nobody sees.
+
+**What it deliberately does not do:** rich-text editing (markdown with a
+preview button instead), a media library, drafts, or editing the generated
+German and Portuguese files. Those stay the pipeline's, and a hand-written
+translation is still frozen with `manual_translation: true`.
+
+#### Worth tightening later
+
+The OAuth application requests no explicit scope, so Gitea grants the default —
+full access to the account, which is more than the editor needs. Narrowing it to
+`read:user write:repository` is a one-line change in `apps/board/gitea.py`'s
+`authorize_url()`, but it invalidates existing authorisations: everyone has to
+approve the app again. Worth doing while the member list is short, and worth
+testing on a throwaway account first, since a wrong scope string breaks sign-in
+for everybody.
+
+#### Removing Decap, once you are confident
+
+Not urgent — leaving it costs a folder and one `wget` in the pipeline:
+
+1. `rm -rf static/admin/`
+2. Delete the `wget … decap-cms.js` line from `.woodpecker.yml`
+3. Delete the `decap-cms` OAuth application in Gitea
