Site-Wide Light-Mode Theme Lockdown
Shipped a strict design-token contract across the marketing site. Every hero, CTA band, card, and content surface now reads from a single set of CSS custom properties — guaranteeing consistent light-mode rendering, locale parity, and WCAG AA contrast.
- New Added --surface-hero, --surface-cta, and --surface-enterprise tokens for cross-page band consistency.
- Improved WCAG AA contrast verified across the English and Spanish locale trees on every hero, body, and CTA surface.
- Removed Removed prose-invert utilities and inline #0f172a backgrounds from all marketing pages. The only legitimate dark surface remaining is the <pre> code block inside help docs.
- Fix Replaced raw AWS execute-api hostname with app.proofco.io in the careers form fallback to eliminate the infra-detail leak.
