Epic: in-app orb editor → parity with the live editor (robust + free)

[mabry1985]

Make the in-app orb editor as robust as the standalone live editor.

Direction change (2026-06-24): for now we route users to the marketing editor (orbis.protolabs.studio/editor/) for orb authoring — see #554 — rather than building a full in-app editor. The in-app Orb tab stays the preset/palette/mood picker. The full-build phases are deferred.

Plan of record: docs/internal/inapp-editor-parity.md (#544).

Status

• In-app editor P0 — unblock & expose (ungate + restore Orb tab) #545 — P0 unblock & expose (ungate + restore Orb tab) — MERGED (feat(orb): unblock in-app orb editor (free) + restore Orb tab #550)
• feat(orb): route to the full editor from the Orb tab #554 — route the Orb tab to the marketing editor — the "for now" answer
• In-app editor P1 — extract editor panes into a shared package #546 — P1 extract panes → @orbis/editor-ui — parked (done on branch feat/editor-ui-package; PR refactor(editor): extract panes + store into @orbis/editor-ui (parity P1) #553 closed, no in-app consumer yet)
• In-app editor P2 — mount the full editor in-app (shader/controls/bindings/meta/json) #547 — P2 mount the full editor in-app — deferred
• In-app editor P3 — unify authoring polish (state/mood deltas in shared controls) #548 — P3 unify state/mood delta authoring — deferred

Revive P1–P3 if/when we decide to build the in-app editor. Related: WebMCP editor tools (#532), gallery (#543).
