Terminal capability matrix
Understand output, input, and fallback behavior.
| Capability | Ink | Cell | Fallback |
|---|---|---|---|
| ANSI color | yes | yes | theme-safe monochrome |
| Mouse SGR | adapter | native | keyboard navigation |
| Bracketed paste | yes | yes | ordinary input |
| Focus reporting | adapter | session | internal focus only |
| OSC 52 clipboard | opt-in | opt-in | application clipboard |
| Alternate screen | yes | yes | inline static output |
Capabilities are detected and reported, never guessed from color alone. Output sessions restore every enabled terminal mode on normal exit and errors.
