Module output 

Pure format functions for every user-facing string.

Zero I/O, zero async, zero radio access. Tested directly with golden strings and the lint. Pure format functions for every user-facing REPL string.

Every function returns a String (or &'static str) - zero I/O, zero async, zero radio access. Testing happens directly on the returned strings plus the accessibility lint.

Accessibility rules

Strings are designed for screen-reader output (blind operators) and fixed-width terminals:

• Label-colon-value format (screen readers parse “Label: value” well)
• Natural-language units (megahertz, watts, hertz — not symbols)
• Booleans as words (on/off, not true/false or checkmarks)
• Lines under 80 characters (no wrapping in standard terminals)
• ASCII printable only (no box-drawing or symbols)
