/* styles.css — the whole visual layer of the mailgun.cz marketing site.
 *
 * What it does: one hand-written stylesheet for `index.html` and `404.html`.
 * No build step, no framework, no CDN — a strict CSP is assumed, so there is
 * no @import, no web font and no remote asset of any kind.
 *
 * What feeds it: nothing at runtime. The colour scale is the owner's ruling
 * «цвета те же» — the brand values are lifegoal.cz's own, measured from its
 * built CSS by the conductor and re-declared here as custom properties rather
 * than copied from its stylesheet. The structural vocabulary (mono tabular
 * figures for anything the system asserts, near-flat elevation, one accent
 * that only primary action wears) is taken from the product's design system,
 * `apps/shared_ui/static/tokens.css`, which this file deliberately does NOT
 * import — the site ships standalone.
 *
 * Where it reaches: `site/index.html` and `site/404.html` only. It is never
 * served to the application at app.mailgun.cz, which has its own stylesheets.
 *
 * What to update on every touch: `site/index.html` (every class name below is
 * emitted there — a renamed class silently loses its styling, since there is
 * no compiler to catch it) and `site/404.html` (reuses `.nav`, `.wrap`,
 * `.btn`, `.foot`). Re-check both widths in a real browser after any layout
 * change: the page must not scroll horizontally at any width.
 *
 * Change ledger
 * 2026-08-11 · claude/email-newsletter-mailgun-a7633b · added: this file
 *   (first revision). Colour scale set from the owner's ruling; light theme
 *   only, because lifegoal.cz is light-only and "the same colours" cannot be
 *   honoured by inventing a dark palette it does not have.
