UX-10 review: the line as logged gets the red-alarm shape, clamp lines at 30 words, plain HA 400
Part 6 checked the quoted reason alone, so title + reason + tails logged
as 4+ sentences. It now also checks the whole line (at most 3 sentences,
none over 30 words); 25 lines failed and are rewritten (one-sentence
wrappers, two-sentence circulation and peak reasons, STALE_READING's
fixed limits on a DEBUG line). The clamp lines for one inverter are
pinned at 30 words with OUTPUT_CLAMP and the numbers kept. Home
Assistant's bare '400: Bad Request' while it loads becomes one plain
line; still WARNING, throttled, a failed write.

"""UX-08: user-facing text follows STYLE.md. RUN: python3 -B test_messages.py
1. Every notification in `app/messages.py` obeys the rule. The test renders
each one with realistic values and checks the title length, the number of
sentences and words for its severity, the banned terms, the entity ids and
the Details line.
2. No notification is worded anywhere else. An AST scan of `app/` fails any
`persistent_notification` call whose payload is not built by
`app/messages.py`.
3. The status page. Every row and banner in `app/messages.py` obeys the rule
for its colour: a row one sentence of at most 15 words, a red row up to 3
sentences and 30 words, a banner at most 12 words.
THE RATCHET for the kinds not rewritten yet. Every status-row and banner
literal left in `app/`, every validator refusal, every WARNING+ log line and every option
name and description in `translations/en.yaml` must either obey its limit
or appear in `ux08_allowlist.txt`. A new string that breaks the rule and is
not listed goes red. So does a listed entry that no longer matches a
failing string, so the list can only shrink: remove the line when you
rewrite the string.
4. DOCS.md has a section for every notification, under "## Notifications".
5. Mutations: each rule is shown to catch a spoiled input (habit 1 of
MUTATION.md).
Run `python3 -B test_messages.py --violations` to print what part 3 sees.
