zk e363bd2532 docs: migrate from mkdocs to mdbook (#1558)
* docs: migrate from mkdocs to mdbook

- Rename old mkdocs docs/ to old-docs/ for reference
- Set up new docs/ with mdbook (book.toml + src/ tree)
- Mirror full nav structure from mkdocs.yml into SUMMARY.md
- Add Justfile-docs with docs-serve, docs-build, docs-check, docs-install recipes
- Import Justfile-docs from root Justfile
- Rewrite .github/workflows/docs.yml: build step uses taiki-e/install-action
  to install mdbook, split into separate build + deploy jobs, PR builds
  run the check step too

* ci(docs): pin actions to SHAs, install mdbook via release binary

* ci(docs): install mdbook from apt instead of curling a release binary

* dev: replace mkdocs python stack with mdbook in dev image

* ci(docs): apt only works on Debian; restore release binary install for Ubuntu CI

* docs: fix duplicate file entries in SUMMARY.md

* docs: remove docs-install recipe

* docs: remove site-url from book.toml to fix asset loading

* dev: install mdbook from upstream release binary, not Debian apt

The Debian package (0.4.x+ds) strips bundled font assets, leaving the
built site without fonts/fonts.css. Use the upstream tarball (same as CI)
so the theme is complete. Handles x86_64 and aarch64.

* docs: vendor mdbook tarballs in dev/mdbook/, install from there

Dockerfile.dev uses COPY + tar to install the right arch at build time.
CI extracts the x86_64 tarball directly from the checkout.
No network access required for either — and no stripped-fonts Debian package.

* fix: unwritten

What are Lamps?

Lamps are a term borrowed mainly from Arcade rhythm games.

Their name is derived from the visual implementation in IIDX and DDR, where a lamp would light up a specific colour depending on how you cleared the chart.

A synonym for this that might make more sense is "clear type", and some games use this name internally.


Examples

In most games, you have a "FULL COMBO", which means you didn't miss. That would be a different lamp to a "CLEAR", which would generally refer to clearing the chart normally.

Another common lamp is "FAILED", which is exactly what you think it would be.

Why Bother?

Some players like to go for lamps, especially in games like BMS and IIDX, where scoring and lamping1 are fairly separate skills. Keeping track of your lamps is important for a lot of games, and generally a cool thing!


  1. Lamping is the colloquial term for 'going for lamps' rather than going for score. ↩︎
