/* New homepage: layout + structure. Every color, font, radius and shadow comes from the CSS variables below.
   A style (static/landing/style-<n>.css) overrides these variables on `body.lp` and may add extra rules scoped to
   `body.lp-style-<n>` (backgrounds, decorations, font-face). Class names in templates/landing/page.html are the contract:
   lp-nav, lp-hero, lp-title, lp-accent, lp-cta-line, lp-btn(-primary|-ghost|-google|-lg), lp-chat, lp-msg(-you|-ai), lp-spark,
   lp-section, lp-what, lp-chips, lp-how, lp-steps, lp-step-n, lp-connect, lp-url, lp-copy, lp-beta, lp-beta-card, lp-foot, lp-fine.
   Fonts must be self-hosted under /static/landing/fonts/ (the site's CSP allows only 'self' for fonts and styles). */
