The whole border breathes in unison: every perimeter cell shares the same fg color and intensity at any moment, both varying as a smooth cosine wave over the period.
The wave shifts the palette index AND the terminal intensity attr,
so the breath is visibly distinct frame-to-frame even on terminals
where :dim and :bold of the same color render similarly. At the
trough the border drops to the dimmest palette color with :dim; at
the peak it climbs to palette[0] with :bold.
Surface support: terminal only. LiveView/MCP currently ignore non-stroke effect types.
