- Extract shared SubdomainNavList used by both subdomain bars
- Add branded Typewriter header to MainLeftBarContent
- Update BACK_TO_FRENO label to 'back to freno.me'
Refactor LeftBar/RightBarContent into main-site and subdomain variants.
Subdomain sites render a simplified, brand-colored shell iterating a new
pure nav-config module (NAV_CONFIG), with a "back to freno.me" affordance
and inline SVG icon resolver. The main site retains its bespoke bars
(Recent Posts, auth-aware nav, admin links, widgets) unchanged.
Add nav-config.ts as an import-free, unit-testable module defining the
per-site link sets (with external/href/auth-gating/icon contract), plus
filterNavByAuth helper and BACK_TO_FRENO link.
Extract pure resolvePageHeadMeta helper that derives title suffix,
canonical URL, and OpenGraph fallbacks from the active site config and
router pathname. PageHead now reads useSite() + useLocation() to
render per-subdomain metadata (e.g. " | Nessa", canonical on
nessa.freno.me) instead of hardcoding " | Michael Freno".
- Always emit a canonical link (explicit override wins; otherwise
https://<site.domain><pathname>)
- Default og:image to the site ogDefaultImage when not provided
- Add unit tests covering all five sites, canonical derivation, and
OpenGraph fallback behavior
