-## Translations
-
-A shipped UI language has three matching parts:
-
-1. `src/i18n/<code>.json` for the card;
-2. `custom_components/houseplan/translations/<code>.json` for the Home Assistant
-   integration;
-3. one registry entry (code, native label and eager dictionary or lazy loader)
-   in `src/i18n/registry.ts`.
-
-Use the canonical Home Assistant/BCP 47 language tag as `<code>` (for example,
-`fr` or `pt-BR`) and use that exact spelling for both JSON filenames. Lookup is
-case-insensitive and also accepts `_` from legacy locale sources.
-
-The registry drives language resolution, the visual-editor selector and parity
-tests. The tests reject missing or extra locale files; frontend dictionaries
-also fail on mismatched keys, empty values and changed placeholders.
-Placeholders such as `{name}` and `{n}` are a contract: do not translate, add
-or remove them.
-
-English and Russian are synchronous fallback/legacy locales. German is the
-reference lazy third-locale implementation: its module carries the same build
-fingerprint as the entry bundle, has one content-hashed retry URL and is listed
-under `lazyLocaleFiles` in `houseplan-assets.json`. New sizeable locales should
-follow that path unless a measured initial-bundle budget explicitly justifies
-an eager import. Extend the runtime, manifest, file/key/placeholder parity and
-regional-locale tests together; never bypass the registry by importing a locale
-directly in a component.
-
-The current `subst()` helper does not implement plural rules. Phrase strings so
-their grammar does not depend on the numeric value (for example, use a neutral
-label followed by `{n}` rather than an English singular/plural pair).
-
-Adding a UI locale does not automatically create another full documentation
-set; maintain the existing English and Russian documentation according to the
-project's normal rules. Right-to-left layout is a separate product project,
-because the plan canvas and editors cannot be mirrored by translations alone.

-### Why `--filter=blob:none` (#345)
-
-A full clone is **215 MB of `.git`**; a blobless one is **26 MB** — measured, not
-estimated. Both carry all 1611 commits and all 182 tags, so ranges, `merge-base`
-and `git diff` across history work identically; `git diff origin/dev~3..origin/dev`
-in a blobless clone takes about a second and grows `.git` by one megabyte.
-
-The difference is that historical *file contents* are fetched only if something
-actually asks for them. That matters here because 32% of the pack is documentation
-screenshots — ten PNGs re-captured 196 times — and another sizeable share is the
-committed bundle, one 1.16 MB file per product change. Almost nobody ever reads an
-old revision of either.
-
-Drop the flag if you work offline with history, or need `git log -p` over the whole
-tree repeatedly. Do **not** replace it with `--depth=1`: a shallow clone is about
-the same size but has no `merge-base`, so the process gate, `smoke-select` and
-every `origin/dev..HEAD` range stop working.

-"""Issue #329 — wall junction limits, Python mirror of src/junction-limits.ts.
-
-The card refuses a WRITE that would ADD a junction violation; this module is
-the backend half of that contract for `config/set` and `plan/optimize` (#333)
-— the two commands a client can use to write arbitrary geometry. Import and
-backup restore are DELIBERATELY outside the gate: #329 §3 promises that a
-restore is never blocked, so a crafted import can still persist violations —
-they are then inherited, never legalised as new ones. It mirrors П1–П4 exactly, including the two legal
-incidences of П4 (a shared node and a T-joint into the middle of a foreign
-wall) and the П3 rule that measures the collinear same-thickness WALL RUN
-rather than one catalogue atom.
-
-П5 (the room keeps at least 25 cm² of interior) is deliberately NOT mirrored:
-it is a statement about the rendered wall bodies, and reproducing the mitre /
-inset pipeline in Python would be a second geometry implementation whose drift
-is a larger risk than the rule it guards. A document that violates only П5 is
-ugly, not corrupt — see docs/specs/329-junction-limits.md §5.

 ```bash
-node scripts/golden-accept.mjs --reviewed --expect-change=wall-junctions-plan-t-dark
+npm run golden:accept -- --reviewed
 npm run golden:verify
 ```

 Never accept images merely to make CI green. A matrix/framing change increments
 `GOLDEN_MATRIX_VERSION`; a normal rendering fix does not. The first canonical
 Linux baseline was reviewed and accepted during the v1.60.3-beta.1 gate.
-
-## Capturing candidates without a second CI round trip (#334)
-
-Accepting from the `golden-images` CI artifact still works and is still the
-safest route: unpack it and pass `--from=...`. It costs two full CI runs per
-visual fix, though — one to produce the artifact and one to verify the accepted
-baseline — and at matrix version 48 that toll is paid often.
-
-A local capture is admissible instead, because admissibility is now *proved*
-rather than assumed. Desktop font rasterisation can differ from the runner, but
-it cannot differ quietly: it would move every text-bearing scenario, not only
-the ones under edit. So the rule is simply that the capture must reproduce every
-accepted baseline the reviewer did not intend to change:
-
-```bash
-node scripts/golden-container.mjs                      # capture in the pinned image
-node scripts/golden-accept.mjs --reviewed --expect-change=<the scenarios you changed>
-```
-
-If the environment is not pixel-equivalent, unrelated scenarios come out
-`different`, the wrapper names them and refuses. A wrong container tag or a
-mismatched font set therefore cannot corrupt baselines — it can only fail.
-
-`scripts/golden-container.mjs` derives the image tag from the `playwright`
-version locked in `package-lock.json`, so the container Chromium equals the
-runner's; `--image=` overrides it when a distro-specific tag is needed
-(`...:v1.62.0-jammy`). The host `node_modules` is shadowed by an anonymous
-volume: the repository copy may be built for Windows, and `npm ci` inside the
-container would otherwise replace it with Linux binaries. The run does write
-`dist/` and the three bundle copies, exactly as a local `npm run bundle:sync`
-would.
-
-Docker is not a requirement of the rule, only a convenience: any Linux
-environment that satisfies the parity condition qualifies, WSL included. The
-`chromium` string recorded in the manifest keeps the browser build itself
-pinned, and `golden:verify` rejects a manifest captured by a different build.
-
-`scripts/golden-accept.mjs` deliberately wraps `demo/golden/accept.mjs` instead
-of replacing its checks: every `.mjs` under `demo/golden` belongs to
-`sourceFingerprint`, so editing the acceptance tool itself would declare the
-committed bundle, the documentation screenshot manifest and the baseline
-manifest stale — the very double round trip this change removes. Narrowing that
-corpus is worthwhile but separate: `scripts/source-fingerprint.mjs` is itself a
-build input, so any change to it forces one bundle rebuild.
+Future updates must still use the `golden-images` artifact produced by the Linux
+CI job as the review set: desktop font rasterisation can differ from the CI
+environment even with the same pinned Chromium. Pass its unpacked root via
+`--from=...` when accepting it locally.

 Scenarios may also declare a semantic pixel region (for example, a receiving
 room that must contain warm light). `golden:capture` and `golden:verify` reject
