**`bun unlink hyperframes` does not exist.** Bun answers "error: bun unlink
{packageName} not implemented yet" — I ran it. The command takes no package name;
it unregisters whatever directory you are standing in. The reader arrives at that
block having just been told to cd into a video project, so even the correct form
would unregister the wrong thing and leave the global link in place — which is
exactly the failure the same page's troubleshooting section then explains. The
page created the bug it diagnosed. Now `cd packages/cli && bun unlink`.
**`data-media-start` and `data-playback-start` are one value, not two features.**
The schema page gave them separate rows with different-sounding meanings, so a
reader would reasonably think they compose. Six read sites in core are all
`playbackStart ?? mediaStart` — runtime/media.ts:18 and :92, runtime/init.ts:751,
1993, 2928, 3010. One row now, alias named, and it says which wins.
**Canary rollouts contradicted itself.** Line 109 called enrolment a pure function
of `(feature, installId, percentage)`; line 195 said canaries bucket on a
dedicated `bucketSeed`, not the telemetry id. The second is right —
cli/src/telemetry/canary.ts:98 is `unitId: config.bucketSeed ?? config.anonymousId`.
Also on the Studio shortcuts page earlier: J/Shift+J for keyframe navigation,
Backspace to delete, and Ctrl+Y for redo were all missing.
Adds the pages the rebuilt navigation is organised around, and moves the sidebar
onto that structure. Every entry points at a file that exists after this commit;
nothing is rewritten or removed yet, and no redirect is claimed yet.
- Studio (13 pages) — the editor had no section of its own
- One guide per creation workflow, matching the shipped agent skills
- Section hubs: Concepts, Catalog, Developers, Deploy, Workflows, Help,
Go further, Product updates, 30 Days of HyperFrames
Pages a later commit retires drop out of the sidebar here but still exist and
still resolve, so the site stays navigable at this commit.
Incidentally fixes a link to /concepts from the Lambda migration guide that is
broken on main today — the destination did not exist.
## Summary
- replace the unsupported `data-var-*` example with the current `data-variable-values` pattern
- document that variable values are carried through but still applied manually inside the nested composition
- add matching reference notes in the data-attributes, HTML schema, core package, and CLI docs
## Verification
- `npx mintlify dev --port 3100`
- browser verification with `agent-browser` on `/concepts/compositions` and `/reference/html-schema`
- proof artifacts saved locally under `tmp/issue-416-docs/`
Major improvements across all 18 pages:
- Use Mintlify components: <Steps> for tutorials, <Tabs> for alternatives,
<CodeGroup> for multi-platform commands, <Tree> for directory structures,
<AccordionGroup> for FAQ/scannable content, <Mermaid> for diagrams
- Add filename annotations to all code blocks (e.g., ```html index.html)
- Add numbered comments inside multi-step code examples
- Show expected terminal output after CLI commands
- Add "When to use" / "When NOT to use" sections to all package pages
- Add "Next Steps" CardGroup to every page (no dead-end pages)
- Cross-link between pages at point of curiosity (not just "see also" dumps)
- Expand thin pages (engine, studio) with architecture details and examples
- Add decision guides (rendering modes, template selection)
- Use <Warning> and <Note> sparingly (max 2-3 per page)
Also adds DOCS_GUIDELINES.md at repo root with writing standards.
