/* Shared styling for the site's secondary pages (currently /donation).

 * ⚠ The tokens below are DUPLICATED from the inline <style> in html/index.html.

 * own hero canvas, carousel and scroll machinery; lifting its stylesheet out
 * would be a rewrite of the page that converts, to save a copy of twelve custom
 * properties. If a token changes, change it in both places — the list is short
 * and the failure is visible on sight.
 *
 * Served from public/, so it is copied verbatim and is NOT hashed. It is linked
