/*
 * Temporary Production landing page. The demo's design values, restated as plain CSS (no application code):
 * src/index.css (@theme colors, radii, Geist), src/site/ui/tokens.ts (DISPLAY_TITLE, SECTION_EYEBROW),
 * src/productShell/foundationPattern.ts (FOUNDATION_GRID), the shadcn Button and Input, SiteHeader and SiteFooter.
 * scripts/landing/__tests__/landingSite.test.ts keeps the colors equal to src/index.css.
 *
 * Phase 1 marketing release (Founder approval, 2026-10-12): the page keeps its basic structure and takes the approved
 * identity: the editorial serif headline (--font-display, the demo's stack) and Option C, Balanced (navy section label and
 * neutral hero wash; Defend Blue stays on the button, links and focus).
