tools/base_tool.py now auto-loads .env at import time so API keys are
available even when tools are imported directly (fixes silent zero-key
fallback in subagents). Added LUMINA bioluminescent terrarium product
ad embed to README. Two new demo compositions: 37 Trillion (one-key
narrated explainer) and LUMINA (music-driven product ad, no narration).
Fix ComparisonCard and CalloutBox dark-theme passthrough in SceneRenderer.
Add 8 demo-props JSON files (3 fixed originals + 5 new compositions).
Update scene-director and compose-director skills with all 10 Remotion
scene types and zero-key rendering guidance. Document the proven
all-dark-background formula in remotion.md. Add cinematic renderer,
onboarding skill, prompt gallery, and demo render script.
