The planned Playwright screenshot docs (SCREENSHOT_AUTOMATION.md) are
replaced by a text standard: screenshots rot silently and cannot be
gate-checked, while this UI's labels are server-rendered templ literals
that can. Layers: pattern-first prose (concepts survive redesigns) >
capability inventory > label->outcome flows > quoted labels > generated
references where a registry exists (filters/fields.md precedent). The
filter docs stay hands-off exemplars; user-doc tone is plain language by
contract, dev/admin tone explicitly deferred.
writing-ui-docs.md is the standard (page template, findability notes,
tone-by-audience, process rule: a UI change is not done until the docs
audit runs). ui-controls.md is the canonical control-label glossary the
docs quote from; TestUIControlLabels greps every entry against
templates/*.templ (source: ts override; also:-fragments for
Alpine-composed labels like the Match/Group header) so renames fail
make test in the same commit as the rename. Gate proven both ways: a
planted bogus label failed; restored set passes.
