- [reference/cookbook.md](reference/cookbook.md) — Curated tour of the most practically-relevant real examples, grouped by purpose: functional pages (media lists, adaptive playback, live data, interaction, plugins) and beautiful layouts (github/extended). Includes deep dives: remembering/resuming playback position (`resume:key`), a server-driven live TV channel list and EPG guide backend, building your own interaction plugin (handler pattern), building your own video plugin (`MyPlayer` pattern), and `layout`-vs-`offset` navigation
- [reference/best-practices.md](reference/best-practices.md) — Two dedicated practical-reference sections not spelled out on any single main-api page: Best Practices (item-type/`"list"`-vs-`"pages"` choices, `transparent`/`background` chains, the grid `image` pixel-sizing formula, `imageOverlay`/icon-contrast pitfalls, `"teaser"`/`"button"`/`"control"` sizing, `tag`/`stamp`/`badge` defaults, compressed header/footer spacing) and Good to Know (why background video/audio keeps playing after `back`, player UI timing, why a `"separate"` item's `layout` height isn't all image/focus space)
- [reference/versioning.md](reference/versioning.md) — Version model, backward compatibility, forward behavior, three version systems
- [reference/glossary.md](reference/glossary.md) — Key MSX terms defined
- [reference/common-misconceptions.md](reference/common-misconceptions.md) — Anti-hallucination reference: plausible-sounding properties/values/actions/versions that do NOT exist, each corrected against the KB (menu `data`/`content:` prefix, grid coordinate/compress traps, `image`+`icon` combination, action version edge cases, and more)
- [reference/settings-reference.md](reference/settings-reference.md) — The native, end-user-facing Settings screen: every panel, its allowed values, how to open/set it from a JSON action, and how a plugin reads it. Covers what the URL Parameters and Settings Menu Item pages don't: which settings are runtime-adjustable vs. launch-only, the Context Menu (Home/Player/Volume/Settings/Exit), and the `layout` `fix:` prefix
