/*
 * cspurl.link trust site — one hand-written stylesheet, served by nginx.
 *
 * Not a Vite build, on purpose: the redirect service ships no front-end
 * pipeline of its own, and six pages plus three error states do not need one.
 * Cache-busted with ?v={APP_VERSION} in the layout.
 *
 * One theme, deliberately. All three supplied logos carry dark lettering
 * (the "CSP" of CSP Geeks, "MAGE" of Mage URL, the Press Mage wordmark), so
 * they sit on light surfaces only; navy is used for the hero and footer,
 * which carry text and no logos. A dark-mode variant would put the logos on
 * navy and erase them.
