/* styles.css — the Launch Club component + layout system.
 * Consumes the design tokens in tokens.css (var(--color-*), var(--text-*), ...),
 * which are generated from clients/launchclub/DESIGN.md. This file is byte-identical
 * across every generated variant — only the copy in index.html changes. Editing the
 * brand = edit DESIGN.md -> re-run export-tokens.js; structure lives here.
 * Every padding/margin/gap/font-size below resolves to a design token — enforced by
 * `npm run validate` (scripts/validate-design.js). Keep it that way. */
