pub const MIN_SAVINGS: usize = 4096;Expand description
Minimum savings (bytes) for the [saved …] indicator-line suffix.
Deliberately independent of SMALL_THRESHOLD/DISPLAY_CAP — the same
4096 value is a coincidence: this is a noise floor on a savings delta,
whereas SMALL_THRESHOLD is the passthrough byte budget.
Below this floor the suffix is suppressed entirely: a [saved 12 B] tag
on every command is noise and would itself waste context. The floor also
subsumes non-positive deltas (summary nearly as long as the input)
and sub-KiB values that humansize would render as 0 B / 996 B,
so no separate rule is needed for those cases.
