The PTY suite runs at one geometry and never under NO_COLOR

[vyncint]

Today — the PTY suite drives the TUI at one geometry, size(110, 32), and never with NO_COLOR. reconverge's suite tests a narrow width, NO_COLOR and ASCII mode; this one does not, so a layout that truncates a verdict at 80 columns, or a colour-only cue that disappears in a monochrome terminal, is not caught.

Fix. Add a second geometry (80×24, the default terminal) and a NO_COLOR=1 run to the existing flows, asserting the verdict, the chosen configuration and the speedup remain whole and readable; keep the "one predicate per instant" sync policy the suite already follows.

Done when

• The main flow passes at 80×24 and under NO_COLOR, with assertions on content, not just absence of panic.
