Applied as-is. The shared Modal keeps Tab inside the topmost dialog, pulls focus back if it leaves, skips disabled, hidden, inert and zero-size controls, and does not trap while a .guide overlay is open. Escape still closes the dialog. Enter is unchanged, so a focused button keeps its native click.
Tests: node --test test/ui/modal.e2e.test.js test/ui/loadout.e2e.test.js test/ui/leftovers.test.js test/ui/match-info.test.js test/ui/loadout.test.js test/ui/playtest3.test.js test/ui/playtest4.test.js test/ui/uiFixes.test.js test/ui/localArt.test.js — 114 pass, 0 fail. The modal and loadout e2e suites skipped because SP_E2E is unset. eslint on the touched files: 0 errors.
