/* Firekeep — shared foundation for every page on the site.
 *
 * Tokens, reset, nav, buttons and footer live here and NOWHERE else. Two pages
 * each carrying their own copy of the palette is how the marketing page and the
 * docs drift apart one hex at a time; the product repo already learned this the
 * expensive way. Page-specific layout stays inline in its own page.
 *
 * The palette is lifted from the product dashboard's Graphite Pro tokens so the
 * product, the page that sells it, and the docs that explain it are visibly one
 * thing.
