Why Sovereign oocat?

Dimension	Conventional Alternatives	openOODA oocat
Security	Ambient filesystem read access	Bounded by &FsReadCap tokens
Highlighting	External regex engines	Pure openOODA lexers (oo, sh, c, json, py, md)
Theming	Hardcoded color palettes	Semantic token styling from ~/.openooda/theme.oot
AI Agents	No agent interface	MCP stdio tools: view_file, highlight_code, list_languages, slice_lines
