#306: instance branding — logo and favicon, cropped in the browser
An instance had no way to look like itself: the top bar said "Dorfteich" whatever the operator called their instance, `instance.name` was never rendered in the running app at all, and there was no favicon anywhere — `index.html` had no `<link rel="icon">` and `public/` held only fonts and theme-init.js. Where the line is drawn, and why: - **The api never decodes an image.** Cropping, scaling and the conversion to PNG happen on a canvas in the browser; the api checks the PNG signature, reads the IHDR dimensions at their fixed offsets and enforces the caps. An image library would put a decoder in front of attacker-supplied bytes AND would have to be carried through the `--network none` offline build. Reading two big-endian integers is not decoding. - **SVG is refused**, with its own error message rather than a generic "not a PNG": it can carry script, and serving it from our own origin would be a cross-site-scripting vector. An operator who tried one should learn that it is deliberate. - **The crop is driven by number inputs, not by dragging.** A drag-only cropper excludes keyboard and switch users outright; a number input is arrow-key operable and screen-reader readable without any custom aria. The resulting pixel size is stated in text, not only drawn as a frame. - **The variant is chosen by CSS, not JavaScript.** `theme-init.js` has already resolved `data-theme` before first paint, so the correct logo is the one painted rather than the one that appears after a flash. Without a dark variant the LIGHT logo carries both themes — the operator's own asset shown unchanged beats one they did not choose (the rule #307 extends to ponds). The settings screen warns; it never blocks. - **The favicon link is static, its resource dynamic.** index.html stays a static file and the api answers with the uploaded icon or a shipped default — that route must never 404, or the browser keeps its generic icon for good. The default is generated by a script from Node's own zlib (`gen-default-favicon.mjs`), for the same offline-build reason. - Both favicon sizes are uploaded together: one source, one crop, so the tab icon and the home-screen icon can never disagree. - Branding is served WITHOUT a session, because the login screen carries it and the browser fetches the favicon before anyone signs in. The admin screen says so — an operator may not expect their logo to be public. - The metadata is not writable through the settings endpoint: it describes bytes on disk, and hand-writing it would claim an asset that is not there. `./data/branding` follows the three-step rule #303 paid for: env default + `data-dirs.ts` entry, compose volume (repo AND the stages on ONE), and the `mkdir`/`chown` line in the api Dockerfile. `data-dirs.test.ts` is new and closes the hole that made #303's variant invisible: the nightly archive skips a missing directory WORDLESSLY, so the fence now demands that every `*_DIR` the backup env declares actually travels in the archive. Verified against the real defect — removing the line fails it by name. Audit catalogue v1.7 (`branding.changed`), carrying `scope` from the start so #307 is the same event with a different scope, not a second id. Verified: api suite 103 files green (a lone `public-api` ECONNRESET under local parallel load, green in isolation — the documented local flake); branding suite 12 tests against a real directory; crop arithmetic unit tests; a11y pack 11/11 in both schemes; /admin measured at 320px with the new section (overflow 0); and the whole flow walked in the browser: upload → crop 780×180 → stored as 512×118 → logo in the sidebar linking home with the instance name as its accessible name → topbar wordmark following `instance.name` → light logo still shown under `data-theme="dark"`. |

#209: pandoc reference documents carry the VS-NfD marking for DOCX/ODT
reference-vs-nfd.docx/.odt ship as derived binaries: the pinned pandoc's
default reference documents plus a header and footer with the marking —
part of the document's page setup, so it repeats on every page in Word
and LibreOffice and is not deletable body text. Source of truth is
scripts/gen-classified-reference-docs.mjs (wording from shared
classificationMarking(); maintenance documented in assets/README.md).
The converter passes reference docs to pandoc-server via in-request
files + reference-doc; the worker attaches them for marked docx/odt jobs
(job option {marking}, as in #208). Unclassified exports pass nothing
and are unchanged (pinned by fake-converter test). Fidelity suite
asserts against real pandoc 3.6 that marked outputs carry the
header/footer parts and unmarked ones do not; per-page repetition
verified via LibreOffice 25.8 headless PDF (5/5 pages, 2 markings each,
both formats). Word: quick manual look pending (sample files in the
workspace), procedure documented in assets/README.md.
