/*
 * wabfit.com — one stylesheet, five pages.
 *
 * The palette is not a new one. It is the app's own `sand` theme, token for
 * token, out of `src/theme/tokens.ts`: the cream ground, the warm browns it
 * writes in, and the amber it acts in. A site that invented its own colours
 * would be a second brand for the same product, and the first thing a person
 * does after installing is come here.
 *
 * The dark variant is the one thing that is not lifted directly. The app's dark
 * theme is iOS greys with a blue accent, and pairing that with the amber above
 * would put two identities on one domain — so the dark here is the SAND theme
 * after dark: warm near-blacks, the same cream for text, the same amber lifted
 * enough to hold on it.
 *
 * No framework and no build step. Cloudflare Pages serves this directory as it
 * stands, which is also what makes it deployable by somebody holding a phone.
