/* RESEARCH page (research.html). A page for a hiring team: use cases with a before/after
   picture and one big proven number each. All 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 section boundaries, with a "+" where they cross the column lines.
   Colours come from css/tokens.css: ink and greys, green (--signal) only for "verified",
   black only for the CTA. No red, no dark panels. */
