An open HTTP technique (not a SaaS, no vendor/lock-in): clients send Accept: text/markdown and the server returns Markdown from the same URL that still serves HTML to browsers — cutting token bloat for agent readers. Copy-paste recipes for Nginx, Caddy, Next.js, Astro, Django, Rails.

## Notes

- Verified via WebFetch (2026-08-27); no vendor/maker/license disclosed (n/a — no lock-in). Do NOT assert a token multiple (the ~10× figure was a secondary source). This registry itself implements exactly this technique (see src/serve.mjs + deploy/nginx.conf.example).
- Curated from the GTM Stacker signal registry (news_registry.json).
