/*
 * entreprenoid.com — one stylesheet, three pages.
 *
 * ⚠️ **External, not inline, and that is the whole reason it exists.** The site
 * was one page with ~40 lines of inline `<style>`. Three pages would have been
 * three copies of it, which is the "a list nothing checks should not be written
 * down twice" failure in CSS form: the third page's dark mode is the one that
 * quietly stops matching.
 *
 * ⚠️ **Still no build step.** No framework, no preprocessor, no purge. The
 * page's speed is part of the pitch -- a site that sells measuring what agents
 * see should not ship a megabyte of JavaScript to say so.
 *
 * ── The palette ──────────────────────────────────────────────────────────────
 * Chartreuse #C6F335 and near-black #161816, from `docs/design/brand/`.
 *
 * ⚠️ **Chartreuse is NOT a link colour on white.** Against #FFFFFF it measures
 * about 1.4:1 -- far below the 4.5:1 floor and, in practice, invisible. It is
 * used here as a FILL (button, rule, marker, underline) with near-black text on
 * it, which is ~13:1 and excellent. In dark mode it becomes the text accent on
 * #161816, which is ~14:1. So `--accent` is deliberately a different KIND of
 * token in each theme, and `--accent-ink` is what you put on top of it.
