/**
 * Headless publisher for all `@shade/*` packages.
 *
 * Use `scripts/publish-shade.sh` for the interactive human flow (token
 * prompt, conflict detection, version bump-on-conflict). This script is
 * the env-driven variant — designed for `DRY_RUN=1` smoke tests, CI
 * pipelines, and any context where prompts are not appropriate.
 *
 * Required env (when not DRY_RUN):
 *   GITEA_TOKEN  — publish token from Gitea (Settings → Applications)
 *   GITEA_USER   — Gitea username that owns the registry (default: Stian)
 *
 * Optional:
 *   DRY_RUN=1    — pack tarballs but do not publish (no token required)

 * the source-pointing form survives in git.
 *
 * Why this lives at publish time instead of permanently: tooling that runs
 * before any build (`tsc --noEmit`, IDE hover, the workspace dev loop) needs
 * `main` to point at source so cross-package imports resolve without a
 * forced build pass. Shipping dist-only is a consumer-facing concern.
