/*
 * sdk.factadte.com — the developer portal's whole stylesheet.
 *
 * WHY ONE FILE. The site is static HTML served under a CSP of
 * `script-src 'self'` with no CDN, so there is no framework, no utility
 * generator and no build step for styles. One file also means the implementer
 * can diff it: when a rule here disagrees with a board, the board is the
 * drawing and this is the contract.
 *
 * SIBLING OF `/api/`. The tokens below are the same values as
 * `apps/web/public/api/docs.css` and `apps/web/src/styles/tokens.css`
 * (Fintech clara, Torogoz). They are copied, not imported — a page outside the
 * Vite bundle cannot import them, and `/api/` already pays the same price.
 * Anything token-shaped that is NOT in `/api/` is marked «portal» below and is
 * new because a multi-page site needs measures a single page does not: a
 * sidebar width, an outline width, a drawer shadow.
 *
 * LIGHT AND DARK FOLLOW THE SYSTEM. There is no theme switch: the portal has
 * no account to store a preference in, and a switch that forgets is worse than
 * no switch. Same decision as `/api/`.
 *
 * NO SYNTAX HIGHLIGHTING, on purpose. Colouring code needs either a client
 * parser (a megabyte of somebody else's JavaScript under a CSP that forbids
 * `eval`) or per-token markup in the generator. Monochrome code on a tinted
 * surface is what `/api/` already does, and consistency with the sibling was
 * the requirement. If it is wanted later, emit `<span class="tok-str">` and
 * friends and add the rules in ONE place, at the end of §10.
