pub fn color_derived_cells(cells: Vec<String>) -> Vec<Cell>Expand description
Wrap a string-cell row in [comfy_table::Cell]s with blue
foreground so derived-metric rows render visually distinct
from the per-thread primary table when stdout is a TTY.
Operators scanning a long compare or show output can locate
the ## Derived metrics rows at a glance instead of relying
on the section header alone.
On a non-TTY stdout the comfy-table builder calls
[comfy_table::Table::force_no_tty] (see
crate::cli::new_table) which strips the ANSI escape
sequences; the rendered output is byte-identical to the
pre-color baseline for shell-pipeline consumers.
Color choice: blue contrasts with both the unstyled primary
table and the perf-delta verdict palette
(Color::Red / Color::Green for REGRESSION /
improvement) — derived rows do not carry a regression
verdict of their own, so reusing the verdict colors here
would conflict with the established convention.
