/*
 * Blog styles. Loaded after the site theme (theme.css) and built only from its tokens: no colour literals here
 * (a test checks), no inline styles anywhere (the CSP forbids them). Every class starts with bl- so the theme
 * and the other sections cannot collide with it.
 *
 * The one idea: every fact carries its source. Rows on the blog home say which bodies a post rests on
 * ("Fuentes: BOE · AESAN"); in a post, each fact has a numbered pill that jumps to its source, and temperatures,
 * the numbers a food handler lives by, show as small chips coloured cold or hot.
 * Motion that answers the reader: the list reflows when you pick a topic, the contents dot rides to the section
 * you are reading, and the one key fact of a post gets a single highlighter sweep as it scrolls in.
