/* RESEARCH page (research.html), rebuilt 2026-10-20 as one page with tabs: what Verified
   watches for, a real example, then the proof. Content sits in the centre column of the
   site's three-column hairline grid (layout.css); the rails stay empty. Full-width hairlines
   only at band boundaries, with a "+" where they cross the column lines.
   Colours from css/tokens.css: ink and greys; green (--signal) only for "Verified"; amber
   (--caution) only beside "Needs a look"; black only for the CTA. No red, no dark panels,
   no shadows. Pictures are black and white only. */
