/*
 * CoopStackOS — marketing site
 *
 * Built from this project's own material:
 *   type      Public Sans + IBM Plex Mono, self-hosted from packages/design-tokens
 *   surfaces  the CSOS surface ladder (#fafafa → #fff, 8px controls, 12px cards)
 *   product   live HTML interface fragments (data-ui), not screenshots of another product
 *   accent    the cooperative green carried from the company brand, used only for action and one phrase
 *
 * The reference point is the register of the v1 site — warm, plain-spoken, product-led —
 * not its layout, its copy or its assets.
 *
 * site/fonts/ holds byte-for-byte copies of codebase/frontend/packages/design-tokens/src/fonts/.
 * That package is the source of truth and the deploy job compares the two, because the Worker serves this
 * directory as its asset root and cannot reach outside it. Keep every URL here relative to site/.
