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.

Round-2 test-only locks tightening lax `.toContain()` to exact equality, mirroring
Ink's `t.is` assertions (all behaviors already at parity):
- cursor-helpers: buildCursorSuffix/buildReturnToBottom/buildReturnToBottomPrefix/
buildCursorOnlySequence exact full output + show/hide cursor constant literals.
- render-to-string: column "Line 1\nLine 2", paddingLeft " Padded", a byte-exact
single-border 20-wide frame, and byte-exact gap wrap ("A B\n\nC") + column ("A\n\nB")
(the trimLines live tests can't catch trailing-space regressions).
- text: OSC-8 link exact bytes; a new RIS/ESC-c strip test (the existing test only
covered the ESC#8 leg).
- box-in-text validation: the exact "Text string \"…\" must be rendered inside <Text>
component" message via anchored regex (catches extra prefix/suffix, not just substring).

A nested <Text> inside a styled <Text> now inherits the ancestor's bold/italic/
underline/strikethrough/dim -- previously those closed at the nested boundary.
Rewrites inline-text composition from merge-down + per-leaf applyChalk to Ink's
wrap-the-concatenation model (squash-text-nodes.ts + render-node-to-output.ts:136):
each Text's own style wraps the concatenation of its already-styled children, so
<Text bold>A<Text green>B</Text></Text> = chalk.bold("A" + chalk.green("B")) --
bold stays open across the green child.
A bare text-leaf now contributes its RAW value (Ink's #text carries no transform);
all styling incl. the effective bg (ownBg ?? inheritedBg) is applied once by the
enclosing Text's wrap. This also makes the nested-inline backgroundColor="" case
match Ink, and is more Ink-faithful for bare text under a <Transform> (no Box bg on
its glyphs -- Ink's Transform doesn't consume backgroundContext), locked by a test.
G52 comment-anchor index handling preserved. Adds 11 exact-byte tests.

#69 added `useAppContext()` as a Vue-native rename of Ink's `useApp()`,
qualified to avoid reading as the Vue application instance. On reflection the
"Context" suffix borrowed the name of an internal grab-bag context and slightly
mislabels the hook — it returns app lifecycle controls, not that context. The
collision worry doesn't hold up: Vue has no `useApp()`, the returned
`{ exit, waitUntilRenderFlush }` is clearly not the Vue app instance, and "App"
in vue-tui already means the `TuiApp` from `createApp()`.
Rename to `useApp()` for full Ink fidelity (same name + same shape), and drop
the now-defunct "App composable" entry from ink-divergences.md — it ceases to
be a divergence.
Internal context cleanup (the grab-bag `AppContext` + the `StdinContext`
duplication) is intentionally out of scope here, tracked separately.
BREAKING CHANGE: `useAppContext()` is renamed to `useApp()`. Replace
`const { exit } = useAppContext()` with `const { exit } = useApp()`.

Ink's `useApp()` returns `{ exit, waitUntilRenderFlush }`. vue-tui previously
exposed only `exit()` via `useExit()` and kept `waitUntilRenderFlush` on the
`TuiApp` handle alone. Align the public surface with Ink: add `useAppContext()`
returning the same pair, and remove `useExit()`.
- thread `waitUntilRenderFlush` into the injected `AppContext` via a hoisted
impl shared by the `TuiApp` handle and the composable, so both resolve
identically
- add `useAppContext()`; delete `useExit()`; migrate all call sites, PTY
fixtures, examples, READMEs and the public-API surface test
- port Ink's two "useApp waitUntilRenderFlush" tests; Ink's third relies on
React concurrent mode (N/A in Vue)
- rewrite the ink-divergences entry: this is now a *naming* divergence
(`useAppContext` vs `useApp`, mirroring `createApp` vs `render`), not a
surface one — and fix the prior wrong claim that Ink's `useApp` returns
stdin/stdout/stderr
The name is qualified (`useAppContext`, not `useApp`) so it doesn't read as the
Vue application instance (`createApp`/`app.mount`) — the same Vue-native naming
choice vue-tui already makes with `createApp()` vs Ink's `render()`.
BREAKING CHANGE: `useExit()` is removed. Replace `const exit = useExit()` with
`const { exit } = useAppContext()`.

* test: add text ANSI sanitization parity tests from Ink (+15)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test: add use-animation parity tests from Ink (+43)
Port 43 new tests from Ink's use-animation test suite covering:
- Multiple animations in sync, different rates, sibling unmount
- Timer cleanup/recreation on unmount and remount
- Inactive animations, timer leak prevention
- Edge intervals (NaN, Infinity, -Infinity, oversized, zero, negative)
- isActive toggle resets, pause/resume cycles
- Frame catch-up, time/delta tracking, reset() behavior
- Newly mounted/activated animations don't inherit elapsed time
- Wall clock monotonicity, getter function isActive support
Uses selective fake timers (setInterval + performance only) so that
render()'s internal setImmediate still works on real clocks. Fake timer
tests read refs directly to avoid Vue scheduler flush timing issues.

* test: add use-box-metrics/measure parity tests from Ink (+16)
Port 16 missing tests from Ink's use-box-metrics, measure-element, and
measure-text test suites. Fix useBoxMetrics to reset metrics to zeros
when the tracked ref detaches (element unmounts or ref switches to null).
3 tests are skipped because vue-tui's useBoxMetrics uses watchPostEffect
(re-runs only when ref.value changes) rather than Ink's layout-commit
listener pattern, so sibling-content and resize-driven re-measurement
is not yet supported.

* test: add screen-reader parity tests from Ink (+11)
Add 11 screen-reader integration tests covering aria-label substitution on
Text/Box, ANSI styling omission, multiple/nested components, null component,
aria-state variants (busy, disabled, expanded), multi-line roles, and
multiselectable listbox.
Also fix component prop bug: Vue normalizes kebab-case prop names to camelCase
at runtime, so props["aria-label"] was always undefined. Switch Box/Text prop
declarations and access to camelCase (ariaLabel, ariaHidden, ariaRole, ariaState).
Add isScreenReaderEnabled option to renderToString() so tests can exercise
screen-reader output through the component pipeline.

* fix: add layout listener so useBoxMetrics updates on resize and sibling changes
Adds a layout listener mechanism to TuiRoot matching Ink's architecture:
- TuiRoot.layoutListeners Set with addLayoutListener/emitLayoutListeners
- emitLayoutListeners called after every yoga.calculateLayout in commit()
- useBoxMetrics subscribes to layout listeners, diffs values before updating
Enables 4 previously-skipped tests.
