Local Dev 6618b38b2d site-sirius-x: use the Sirius.X brand mark, drop trailing slashes
Star emoji swapped for the site's own 4-point sparkle mark — same SVG
that ships as the favicon — everywhere it appeared: the topnav brand,
the hero mark, the "you're here" pill on the family-of-.x panel, the
footer, register.html, portal.html, tld.html, market/, docs/, admin/,
brand/, storage/, theseus/, studio.html, site-footer.js. Anyone who
opens Sirius.X now sees the acid-green sparkle instead of a browser
star emoji.

Internal links normalised to no trailing slash — href="./theseus/"
became href="./theseus" (Theseus, docs, market, admin). Cleaner URLs
in the address bar and no double-slash redirect step on the mirrors.

// Sirius.X font picker — reader chooses between Fraunces (Silent Mode
// family — editorial serif, default) and Ubuntu (Bitcoin Cash brand
// font — humanist sans). Persisted in localStorage under 'sirius-font'.
//
// The runtime attribute goes on <html> — pages that want to opt out
// simply omit the include. The actual font-swap CSS is defined per
// page (in each page's <style> block) so it can override the page's
// own font-family declarations at high specificity; this script only
// toggles the attribute and paints the picker UI.
