 `uv sync` creates/updates the `.venv` from [`pyproject.toml`](./pyproject.toml) and `uv.lock`, which already includes `teedoc` and all plugins used by this site (so `teedoc install` is not needed).
 Install [uv](https://docs.astral.sh/uv/) first if you don't have it.
 
+### Why `--depth=1`
+
+This is a documentation site, so most of the repo is images. Git keeps every past revision
+of every one of them forever, including large originals that have since been replaced by
+compressed versions. A full clone therefore downloads roughly **1 GB of history** even
+though you only ever need the current version of each file.
+
+`--depth=1` fetches just the latest commit and skips all of that. Editing docs and opening
+a pull request works exactly the same from a shallow clone. Use a full clone only when you
+actually need the history (`git log`, `git blame`, `git bisect`) — you can always deepen a
+shallow clone later with `git fetch --unshallow`.
+
+When adding images, please keep them small (ideally under 300 KB, 500 KB max): anything
+committed here stays in the history for good, so an oversized image costs every future
+contributor bandwidth even after it is deleted. See [AGENTS.md](./AGENTS.md) for the full
+image and authoring guidelines.

+#!/usr/bin/env python3
+"""Check that every image referenced by the docs actually exists.
+
+Broken image links are easy to introduce (moving an assets/ folder, deleting a
+file without touching the pages that use it) and hard to notice, because the
+published site keeps serving stale copies that were uploaded by earlier builds.
+This script catches them at CI time instead.
+
+Only real image references are checked: markdown ``![alt](path)`` and HTML
+``<img src=...>``. Fenced and inline code is stripped first, so example commands
+like ``convert in.jpg out.jpg`` are not mistaken for links.
+
+Usage:
+    python3 tools/check_image_links.py            # fail on anything not in the baseline
+    python3 tools/check_image_links.py --list     # print every broken link
+    python3 tools/check_image_links.py --update-baseline
