   LANDING — the public marketing page (index.html, served at /)
   ----------------------------------------------------------------------------
   Self-contained on purpose. style.css is the application stylesheet (7k lines
   of workspace chrome, body scroll locks, inverted-colour mode); the marketing
   page shares only the brand tokens with it, so it carries its own sheet.

   Built from resources/0-website/BUILD-landing-option-b-html.md. Seven
   full-height panes: cover, reframing diligence, the problem, the new problem,
   the solution to both, the platform, next step. Type is Inter at light
   weight; ice blue carries emphasis. Modals and lead capture come from
   js/lead-forms.js; analytics from js/consent.js.
