Add a parallel handoff path for users of [Open Design](https://github.com/nexu-io/open-design),
the Apache-2.0, local-first, BYOK alternative to Claude Design that drives whichever
coding-agent CLI the user already has on their PATH (Claude Code, Codex, Cursor, Gemini,
OpenCode, Qwen, Copilot, Hermes, Kimi, Pi).
Mirrors the existing Claude Design integration:
- README: a paragraph next to the Claude Design one, pointing at the new guide and
explaining the drop-into-skills/SKILL.md install path
- docs/guides/open-design.mdx: Mintlify page parallel to claude-design.mdx, with
Steps, comparison table, prompts, limitations, handoff
- docs/guides/open-design-hyperframes.md: SKILL.md-shaped instruction file users
drop into skills/hyperframes-handoff/SKILL.md (Open Design auto-discovers it
on next request) or attach to chat as a one-shot
- docs/docs.json: nav entry for the new page
The instruction file deliberately defers to claude-design-hyperframes.md as the
canonical reference for skeleton catalogs, shader patterns, HDR, and audio-reactive
animation — it stays focused on what Open Design's prompt stack needs at emission
time (active-DESIGN.md binding, 5-dim self-critique gate, structural rules) so the
two guides don't drift.
Open Design already ships a motion-frames skill that says "hand-off ready for
HyperFrames" — this PR closes the loop on the HyperFrames side so the route is
discoverable from the HyperFrames docs.
