/* site.css - Telegrapher. Derived from the skillfed.io portal design system
   (skill-federation-mvp/seo/portal/generate/assets/site.css + pages.css + gist.css):
   same 3-column rail shell, card/rowlist/keynums/editorial vocabulary, system font
   stacks and cascade law (responsive tiers LAST). Re-voiced for a research group:
   brass + signal red on paper, one signature device - Morse dot-dash strips
   (.morse) - and everything else kept quiet.
   Accent families: brass (Telegraph English), signal (error trilogy),
   patina (reasoning), steel (applied). Text on a tint always uses the -ink token. */
