Remove the revert and unset keywords, vw/vh units, the |= and $= attribute
matchers, :nth-child(... of ...), the stylesheet analyzer and the
engine-unsupported warnings. inherit and initial remain the CSS-wide keywords.
With Custom Styles open, clicking a section or entry on the page adds a
rule for it under a comment naming it (or moves the cursor into its
existing rule). While the cursor is in a rule, everything it matches is
outlined on the page. Autocomplete offers sections and entries by name
and inserts their selector, instead of escaped UUIDs. The guide gains a
Style one element section, including the :nth-of-type form.
Custom styles no longer need @version 1; at the top: the language
version already lives beside the text, so new and converted stylesheets
leave it out, the editor hides it in older ones, and the compiler
ignores it. The validity status and inline diagnostics are gone too:
whatever applies shows in the preview and anything else is left out.
Rewrites the landing page, in-app microcopy, and public docs, then fixes what the rewrite exposed: stale template counts, a broken quickstart anchor, out-of-sync FAQ structured data, dead error-hint branches in the MCP tools, and wrong-sense translations across all 53 locales. Adds GLOSSARY.md so translators get the right sense of the ambiguous UI terms.
