"""UX-13 P5: the page's words, English and Dutch, follow STYLE.md.   `python3 test_ui_text.py`

app/ui_text/en.json and nl.json hold every word the Home, Batteries, Settings
and Setup screens show that is not an option label (those are
translations/*.yaml, test_translations.py) or a status row (app/messages.py,
test_messages.py). This check fails CI and names the offending string when:

1. the two files differ in keys, or a string's {placeholders} differ;
2. a string breaks STYLE.md: a name or label over 6 words, a description over
   1 sentence of 25 words, any other line over 2 sentences, a semicolon, a
   banned or jargon word (English and Dutch lists), an option key or entity id;
3. a string carries its own details (a link, a section number, a file name)
   instead of leaving them to the page's DOCS link;
4. Home's sentences, rendered by app/homeview.py in each language, break
   the Home rules of test_messages.py part 8 (checked there too);
5. a Dutch string is left in English, outside the short list of words that
   are the same in both;
6. the English words that mirror app/messages.py drift from it.
Each rule is shown to catch a spoiled input (habit 1 of MUTATION.md).
