/*
 * US Fax Number Validator — styles.
 *
 * WPCode snippet 7790 "US Fax Number Validator CSS", verbatim, from
 * data/wpcode-snippets-export-2026-09-04.json. Live injects this INLINE in the
 * head; we serve it as a file so the two pages that need it can share one
 * cached copy instead of carrying 4,377 bytes of HTML each.
 *
 * Loaded ONLY on /how-to/fax-number-examples-and-formats/, from src/pages/how-to/[slug].astro.
 * Live scopes it the same way, by URL condition:
 *   "page_url contains /fax-number-examples-and-formats/"
 * Do NOT move this into cf.css / the shared bundle — see CLAUDE.md.
 *
 * ---------------------------------------------------------------------------
 * ONE SELECTOR IS NOT VERBATIM: `.cf-page .usv-title`. THE DELIVERY CHANGED THE
 * CASCADE.
 *
 * Live injects this sheet INLINE IN THE HEAD, AFTER the cf- CSS. `.usv-title`
 * and `.cf-page :where(h3)` are both (0,1,0), so the tie goes to source order
 * and live's title renders 28px/700. We serve the same bytes as a FILE that
 * loads BEFORE the cf.css bundle, which reverses the tie. Measured against
 * live at 1280: ours 25px/600 against live's 28px/700.
 *
 * Scoped up to (0,2,0) rather than reordering the sheets, because reordering
 * fixes this one title and leaves the mechanism live for the next sheet we ship
 * that live inlines. The h3 base keeps its `:where()` — it is a default many
 * components want to override, which is why it carries one. No `!important`.
 * CLAUDE.md rule 1, the second of its two fixes; rule 2's seventh instance.
