One reference page per panel. Every page follows the same shape so you can predict where to look:
- Purpose — what task it really solves.
- Where it is — URL, nav location, accesskey to reach it.
- Quick start — minimum-viable usage in 5 numbered steps.
- The interface — every visible field and button on the page.
- How it integrates — Send-to producers and consumers.
- Engines — which of the six request engines apply.
- Keyboard map — every accesskey on the page + relevant globals.
- Accessibility notes — read order, ARIA roles, AAA-specific patterns.
- Recipes — 3-6 worked examples with real syntax.
- Troubleshooting — known gotchas.
- CLI equivalents (where any).
- Storage footprint — what gets persisted into the
.rlrand under what key.
