1. Fix pclass.title() underscore bug in scaffold headings (216+ files)
2. Add 5 extended classes to batch.py valid_classes set
3. Add atmosphere rim colors for cold_arid/hot_arid/tropical/boreal/temperate_terminator
4. Add cloud/tilt ranges for extended classes (boreal 55-75%, tropical 60-80%)
5. Fix legend overflow at 1024px + deduplicate rainforest labels
6. Move _check_habitability() inside loop (was only checking last body)
7. Preserve gas_giant_ringed distinction in profile table
8. Drop meaningless terrain fields from gas giant frontmatter
9. Update stale docstrings/comments for 1024x512 default
10. Add infernal ring color
All lookup tables (CLASS_TILT, CLASS_CLOUD, CLASS_POLAR_ICE, CLASS_GEOTHERMAL,
CLASS_OBLATENESS, atmo_colors, tectonic_map, substrate_map) now include the
5 extended planet classes. Body content requires full regeneration.

The atomic .tmp→rename pattern caused silent FileNotFoundError on some
bodies. Removed in favour of direct writes — resume logic already handles
interrupted runs. Fixed --heightmap-size CLI flag which was silently
ignored due to Python default parameter binding. Changed default heightmap
resolution from 4096x2048 to 1024x512 (native simulation grid — no
information gain from upscaling).
