/* FeedLead support-page design system
 *
 * WHY THIS FILE EXISTS
 *   2026-10-03. /about/, /definitions/, /press/ and /blog/ each carried their
 *   own inline stylesheet and had drifted apart -- different footers, different
 *   spacing, three of them still on a 2025 copyright. They are not sales pages
 *   and should not each be rebuilt as one, but they do have to feel like the
 *   same product as / and /pricing/.
 *
 *   The tokens below are copied from the live homepage so the support pages
 *   inherit the brand rather than approximate it. Text-first, no animation, no
 *   decorative JavaScript: these pages are read, and increasingly they are read
 *   by machines that do not run scripts.
