1. Add 5 extended atmosphere colors to biomes.toml (globe renderer reads
from toml, not body_def) — cold_arid, hot_arid, tropical, boreal,
temperate_terminator. Remove dead martian entry. Slightly differentiate
colors from base classes.
2. Fix profile table raw identifiers — apply .replace('_', ' ') to class
field in wiki body pages.
3. Fix legend text overflow — truncate labels with ellipsis when step
size is too narrow for full text.
4. Fix title panel underscores — use .replace('_', ' ') instead of
.replace('_ringed', '').
