README is now a landing-page-style entry point: centered hero banner,
badges, tagline, feature grid, architecture diagram, self-hosting
table, stack rationale, quick start, project layout, testing summary,
docs index. Image placeholders reference docs/assets/{banner,
dashboard-preview,admin-preview}.png with sizing guidance in
docs/assets/README.md.
docs/INTERNAL_API_AUTH.md walks through the bearer-token model the
worker uses to call /api/v1/internal/* endpoints: where the token
lives on both sides, the constant-time compare, fail-closed semantics
when INTERNAL_API_TOKEN is unset, and the planned per-worker JWT
upgrade path.
docs/VENDOR_LOCKIN.md is the honest scorecard: each external
dependency (AWS KMS, DynamoDB, S3, Cloud Tasks, Stripe, Turnstile,
Sentry) gets a row covering self-host status, alternatives, and what
'free of this dependency' actually looks like. Includes the minimum-
viable self-host env-var set.
