+// Package gitea is a stdlib-only client for the Gitea API (JSON over
+// /api/v1). It exists so the harness, the loop, and every vertical talk
+// to the forge through one Go library instead of shell glue: repo
+// create/list, branch list, commit statuses, and the full pull-request
+// flow (create/list/merge) — the surface the turn harness needs to land
+// work via PRs.
+//
+// Security discipline: the token travels ONLY in the
+// "Authorization: token <key>" header. Response bodies are never
+// surfaced in error strings (a server echo is assumed to be able to
+// carry the token), so errors are one-line, parseable
+// "sentinel: http NNN" shapes.
