/**
 * Styles of the FilmNatale landing page.
 *
 * Why these choices:
 * - Colors are the app's "cinema" palette (`app/src/theme/tokens.ts`): the page is the `notte`
 *   green the user asked for, accents are `oro` (on notte the design system never uses red text)
 *   and the one red button per screen is `rosso`. No other colors appear in the rules below.
 * - Fraunces for titles, Figtree for everything else, the same files as the app.
 * - Side margins follow the app's layout classes: 16 px below 600, 24 up to 899, 32 above.
 * - The hero is a size container, so every object is placed in `cqw`/`cqh` (fractions of the
 *   hero itself) and the burst keeps its shape on any screen; portrait and square screens get
 *   their own arrangement so nothing lands on the payoff.
 * - The burst is driven by one registered number, `--e` (0 at the center, 1 in place), so the
 *   entrance, the overshoot and the scroll parallax (`--p`, set by main.js) share one transform.
