This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- supportsColor exports supportsColor function and stdout/stderr stream inspectors
- supportsColor returns false for non-TTY streams when FORCE_COLOR is unset
- supportsColor respects FORCE_COLOR levels 0 through 3 and boolean values
- supportsColor detects truecolor support when COLORTERM is set to truecolor
- supportsColor detects 256 color support when TERM is set to xterm-256color
- supportsColor suppresses color when TERM is set to dumb
- getColorSupport helper forwards stream checks and returns color level details
