   Signal Loom — sloom.studio shared stylesheet
   "Instrument" design system — mirrors index.html so docs / examples /
   privacy read as one crafted site, not a template. Inner pages keep their
   own page-specific inline <style>; this file supplies the shared shell
   (tokens, top bar, footer, buttons, tags, typography) + legacy var aliases
   so the existing inline rules keep resolving.
