Why: Make the renderer architecture, implementation plan, design rules, workflows, and acceptance matrix reviewable from the active two-trees task. Evidence: SELF checks validated all relative links, code fences, JSON syntax, manifest hashes, and staged whitespace at Documents 647da985774983fb12dadf2073f68efb9046151f. Impact: Updates only the Documents gitlink and active task-card reference; no product code, migration, deployment, or published rules change. Refs: feature/rdm-two-trees-latest-templates
