Value-audit verdict: the file is already well-factored (~6% genuine bloat).
Merged: 7 full-modal renders for experimental-feature labels into 1;
read-only default-render clusters (Global General defaults, version
display, header actions); export-filename negative folded into positive.
All original assertions survive verbatim; 2 mutate-to-prove checks confirm
merged tests still bite; lane green 3x with no flakes.
Honest note: wall-clock neutral (~47s lane) — per-test cost is dominated
by the ~60-stub beforeEach + full-modal render, not duplicate assertions.
A 30-40% lane reduction requires structural work (shared mock fixture,
subtree renders) deliberately not attempted here (correctness risk).
