Decision 3 (MDX content plus Sanity) is superseded by 0114: the page builder builds every page, our own site included. Decisions 1, 2 and 4 stand.

​
Context

The landing site is public and must be indexable, so unlike the console (0052) it needs prerendering. React Router 7 framework mode provides that and keeps one router family across web surfaces. Marketing content changes more often than code.

​
Decision

  1. The landing app uses React Router 7 framework mode with an explicit routes.ts (code-based, no file routing, per 0053) and prerenders public pages.
  2. It deploys to Cloudflare Workers (0063).
  3. Content is MDX in the repository plus Sanity for editor-managed content. The Sanity project and token names are TODO; token values live in the vault.
  4. The landing app is a new tier:app member (apps/landing), created with pnpm new.

​
Consequences

  • Fast, indexable pages; editors can change Sanity-backed content without a deploy.
  • Sanity is a new external service and cost.
  • Framework mode is the one place a server runtime (Workers) appears among web apps.

​
Enforcement

Planned — the pnpm new scaffold and a CI build with prerender; the no-file-routing check from 0053 covers routes.ts.
