Regression tests for behaviors the audit found correct-but-unpinned, so the
suite is a strict superset of Ink:
- A07: two <Static> regions both render (the additive divergence)
- B04: Static render-prop index = absolute index across appends; container
vertical padding adds blank rows to the static frame
- B11: lazy raw-mode acquire/release under rawMode:'auto' (the path the
'always' default masks)
- B19: child useCursor unmount emits the cursor-hide escape (stream-level)
- B20: animation interval 0/negative clamps to 1ms (normalizeInterval unit) and
advances without busy-hang
- B21/B28: INK_SCREEN_READER env auto-detection + useIsScreenReaderEnabled
true-path (env tests isolated in a *.sequential file per the global-state rule)
- B29: renderToString serves useCursor/usePaste/useTerminalSize/useAnimation/
useBoxMetrics as inert no-ops (don't throw)
- B30: dedicated columnGap/rowGap props + their removal-reset
Test-only; no production changes. Codex-reviewed for non-vacuousness, Ink
correctness, and process-global isolation.

normalizeInterval rounded the interval (Math.round), so a 60fps interval (16.67ms)
became 17ms and 8.4ms became 8ms — drifting frame=floor(elapsed/interval) and the
scheduler's nextDueTime over time. Ink's normalizeAnimationInterval
(use-animation.ts:147-151) does not round. Removed Math.round; the clamp
(>=1, <=MAX_TIMER_INTERVAL) is unchanged and the scheduler already ceil()s the
setTimeout delay so a fractional interval doesn't busy-loop.

Enable sequence.concurrent: true in vite.config.ts so the non-PTY suite runs
concurrently like the PTY suite. Stress-verified stable (8/8 at maxForks=4);
the suite drops from ~13s to ~4-5s.
Three test patterns were incompatible with concurrency; handled per cause:
- Inline snapshots (background-color, borders): the module-level `expect`
loses snapshot test context under concurrency. Fixed in place by using the
context-local `expect` (async ({ expect }) => ...), so they stay concurrent.
- Process-global state (throttle/animation-scheduler use fake timers; leak
asserts on process exit/SIGINT listener counts and live yoga nodes): a
concurrent sibling clobbers the shared global mid-test. These genuinely
require serial execution, so they move to *.sequential.test.* files with
it.sequential / describe.sequential and a header explaining why.
`vp run ready` passes.
