/* SPREETZ-PUBLIC-MARKETING-HOMEPAGE-01 — public marketing surface.
 *
 * Tokens below mirror apps/mobile/lib/theme (colors.ts / tokens.ts) so the public site and the app
 * read as one product. They are COPIED rather than imported: the marketing surface is deliberately
 * dependency-free static HTML/CSS with no build step, and importing the app's TypeScript theme
 * would couple a public page to the authenticated app's runtime. Values that must stay in step:
 * navy #0d1b3e, teal #0e7a68, blue #0068a8, green #1f9d57, and the 4-based spacing rhythm.
