/* reposta landing (issue 0111) — Diseño aprobado: canvas
 * https://claude.ai/artifact/DShWXNhiWev2RhDtP4ByAE, tableros "Elegida · B
 * con el dato de C" (móvil) y "Elegida · escritorio", más "Común ·
 * secciones bajo el inicio". Plain HTML/CSS, no build, no framework — the
 * one script is the hero scene (issue 0112, ADR-0020; `.hero`/`.scene`
 * below), and the page is whole without it. Colour
 * tokens copied from web/static/app.css's dark theme (not shared — the
 * landing must not depend on the app, nor the app on it). Night only: the
 * mockup is fixed dark, no light variant.
 *
 * One `index.html` is the B mobile layout on phones and the Escritorio
 * layout at the --desktop breakpoint (CSS only, no JS): the shared lower
 * sections (trust line, diferenciadores, cómo funciona, FAQ + quién la
 * hace, footer) reflow with flexbox/grid. Since 0112 the hero (headline +
 * scene with its maths) leads, and the "top" band below it is the captura
 * of the same search then la beta — stacked on mobile, side by side on
 * desktop. */
