 COMMAND:
-Apply APPLY_PR_DEBUG_SURFACES_PRESETS and APPLY_PR_DEBUG_SURFACES_ADVANCED_UX
+Create PLAN_PR_DEBUG_SURFACES_3D_SUPPORT
 
 Requirements:
-- Execute both APPLY PRs in sequence
-- Do not introduce new features
-- Preserve behavior parity
-- Use existing public APIs only
-- Validate after both APPLY steps
-- Do not refactor unrelated systems
-- Keep project-specific logic outside engine-debug
-- Ensure preset system and advanced UX integrate cleanly
-- Maintain persistence compatibility
+- Follow PLAN_PR -> BUILD_PR -> APPLY_PR
+- Docs-first only
+- One PR per purpose
+- Plan the first reusable 3D support layer for the debug surfaces platform
+- Define shared 3D panels, shared 3D providers, optional 3D presets, adapter boundaries, adoption models, naming conventions, and target structure
+- Keep the first version summary-level and opt-in
+- Exclude renderer-specific implementations, deep inspectors, and network support from this PR
+- Keep project-specific renderer/scene adapters outside the shared layer
+- Write outputs under docs/pr and docs/dev/reports
+- Put codex command and commit comment under docs/dev
+- Update BIG_PICTURE_ROADMAP.md by changing bracket states only
+- Package to <project folder>/tmp/PLAN_PR_DEBUG_SURFACES_3D_SUPPORT_delta.zip
