// c21 — handler: /contributing reads ./CONTRIBUTING.md from the repo
// root and renders it through the docs layout. Mirrors the shape of
// other content-driven pages (samaLandingHandler, blogLandingHandler)
// but reads from the project-meta root file rather than from a
// per-section content/ subdirectory. The file is also browseable at
// /GIT/tdd.md/blob/main/CONTRIBUTING.md via the SAMA-native source
// viewer — same content, two URLs.
