Standalone renderer path with no terminal bindings. Captures Static
output, provides no-op contexts for hooks, proper WASM cleanup.

Add four behavioral surfaces to the runtime:
- patchConsole (default: true): intercepts console.* methods to route
output through writeToStdout/writeToStderr, preventing frame corruption.
Disabled in debug mode. Restored before Vue cleanup on teardown.
- waitUntilRenderFlush(): flushes pending throttled renders and waits
for the stdout write barrier, exposed on TuiApp and testing RenderResult.
- onRender callback: fires after each commit with { renderTime } in ms.
- maxFps option: overrides the scheduler's default 32ms throttle interval
with 1000/maxFps. The scheduler now accepts a throttleMs option and
exposes hasPending() for flush coordination.

- Add style prop to Static (default: position absolute, flexDirection column)
- Apply style props to isolated static paint (padding, flexDirection, etc.)
- Track staticNode/previousStaticNode for identity changes
- Reset fullStaticOutput on Static unmount/remount

- Replace data event with readable + input-parser state machine
- Intercept \x03 in input pipeline (not process SIGINT)
- useInput now uses parse-keypress for semantic key mapping
- 20ms pending escape flush timer matching Ink
- Esc focus reset in input pipeline

Wrap user root component in an InternalErrorBoundary that catches all
descendant errors (setup, render, lifecycle) via onErrorCaptured and
routes them through exit(error). This prevents yoga WASM state corruption
that occurred when errors propagated uncaught during Vue's render phase.
- Add ErrorOverview component for rendering error frames
- Replace try-catch around mount with onErrorCaptured boundary
- Update testing render() to detect early exit errors
- Convert 3 todo tests to active tests (nested setup, unhandledRejection, post-mount)

Change Box-in-Text validation from dev-only warn+skip to unconditional
throw, matching Ink's reconciler behavior. Add text-outside-Text
validation that throws when non-empty text-leaf nodes are inserted into
box/root/static containers outside a Text context.

Transforms were appended (`[...transformers, node.transform]`) causing outer
transforms to execute before inner ones. Ink prepends so inner transforms run
first and outer transforms wrap the result. Adds a nesting-order regression test.

Port Ink's output character model using @alcalzone/ansi-tokenize. Each cell is now a
StyledChar with proper grapheme clustering. Fixes emoji alignment, wide char boundaries,
and changes clipping to top-only (matching Ink). Upgraded ansi-tokenize to ^0.3.0.

Detect invalid <Box> inside <Text> nesting at the DOM insert level and
emit a dev warning instead of crashing the WASM yoga engine. The box
insertion is skipped to prevent layout corruption.

Match Ink's behavior where Newline renders as ink-text (yoga carrier).
When inside a Text parent, Newline still renders as virtual-text for
inline behavior. When standalone, it renders as a text node so it
participates in yoga layout and occupies vertical space.

Vue's errorHandler (installed after mount) already catches render-time
errors from nested components and routes them through exit(err),
providing error boundary behavior matching Ink's design.

Write ESC[?25l to stdout after mount and ESC[?25h during teardown,
matching Ink's cursor management. Only active in production mode
(debug: false) to avoid interfering with test streams.

Transform nodes now participate in yoga layout with flexShrink=1,
flexDirection='row', matching Ink's Transform which renders as ink-text.
This fixes multi-line text under Transform not getting proper layout
height. Transform nodes inside Text parents remain inline (excluded
from yoga tree) to preserve renderTextWithInlineStyles behavior.

Add leading+trailing throttle to the commit scheduler in production mode.
In debug/test mode (immediate: true), commits fire without delay to
preserve test determinism. Adjusted the non-debug static test to account
for the throttle timer.

Set flexDirection=row, flexShrink=1, flexGrow=0 on text yoga nodes at
creation time, matching Ink's <ink-text> style defaults.

Yoga's measure function already receives the content-area width (minus
parent border/padding), so text wrapping is correct without additional
adjustment in the paint pass.

Match Ink's Box defaults by setting yoga properties at node creation time.
This ensures proper row-based layout regardless of Vue's prop patching order.
Updated affected test snapshots and added explicit flexDirection="column"
where tests relied on the old column default.

Add parsing for Home (ESC[H, ESC[1~, ESC[7~), End (ESC[F, ESC[4~,
ESC[8~), Ctrl+arrow (CSI 1;5 A/B/C/D), and Meta+arrow (double-ESC
prefix) key sequences. Add home/end fields to the Key interface.
Implement 12 new useInput tests for these key combinations.

Change exit(error?: Error) to exit(errorOrResult?: unknown). When an
Error is passed, waitUntilExit rejects; otherwise it resolves with the
value. This matches Ink's behavior where exit("hello") resolves the
promise with "hello".

Update renderTextWithInlineStyles and flattenLeaves to handle transform
nodes nested inside text elements, matching Ink's squashTextNodes
behavior. Skip transform application on empty text to avoid wrapping
empty strings. Skip writing empty text nodes to avoid applying line
transformers to empty content.

Add independent horizontal/vertical clip support in the paint pass,
matching Ink's per-axis overflow behavior. Add overflowX/overflowY to
STYLE_PROPS so they are stored in el.props for the paint pass.
Implement 26 new overflow tests translated from Ink.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Guard flattenLeaves and renderTextWithInlineStyles to skip comment
nodes (produced by Vue for null/undefined children) and return empty
strings for childless text nodes. Also guard bindTextMeasure to return
zero dimensions for empty text. Expand TuiInlineNode to include
TuiComment since Vue inserts comments into text containers.

"constructor" in {} returns true because it hits Object.prototype.
Using Object.hasOwn ensures only actual yoga prop keys are recognized.

AGENTS.md requires shallowRef by default. All test state uses
reassignment (not mutation), so shallowRef is correct.

Ink's wrap mode uses { trim: false } to preserve leading/trailing
whitespace on wrapped lines. We incorrectly used trim: true which
stripped whitespace. Updates unit test and inline snapshots.

Port Ink's clip/unclip approach to vue-tui's paint output. When a box
has overflow="hidden", content painted by its children that falls
outside the box's content area (inside borders) is clipped.
Implementation:
- Add ClipRect, clip(), and unclip() to the Output class
- Maintain a clip stack; active clip is applied to each write op
- Horizontal clipping uses slice-ansi for correct ANSI handling
- Vertical clipping slices the lines array
- Store "overflow" in STYLE_PROPS so it's available in node.props for
the paint pass
Also adds explicit flexDirection="row" to two overflow tests where
multiple child boxes should lay out side-by-side (Ink defaults to row,
vue-tui defaults to yoga's column).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Ink's Box defaults to flexDirection="row", so multiple <Text> children
lay out side-by-side. Vue-tui uses yoga's default (column). Rather than
changing the global default and breaking 20+ existing tests, add
explicit flexDirection="row" to the inner boxes in these two tests so
they match the intended layout behavior being verified.

The space-around alignment distributes space as 1-row gap / AB / 2-row
gap / CD / 1-row gap for a 6-row container with 2 content rows.
Expected value was "\nAB\n\nCD\n\n" but Ink produces "\nAB\n\n\nCD\n".

height=6 containers produce 6 lines. Ink's renderToString returns
"A\n\n\nB\n\n" (preserving trailing blank lines). The tests incorrectly
expected "A\n\n\nB" with a comment claiming lastFrame({ trimLines: true })
trims trailing newlines — it does not; it only trims trailing spaces per
line.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Ink's Output.get() calls .trimEnd() on each line of the rendered grid.
Without this, vue-tui's paint grid always fills the full root width with
spaces, causing raw frame output to contain 100-char-wide padding. This
broke tests using { raw: true } and made meaningful trailing-space
assertions impossible with { trimLines: true }.
Also corrects test assertions for 'set width in percent' and 'relative
position' that expected trailing spaces which Ink never produces.

Covers basic character input, arrow keys, return, escape,
backspace, tab, and isActive option.

Distributes across text, static, transform, newline-spacer,
error-handling, and prop-reset test files.
Tests requiring features not yet in vue-tui are marked test.todo:
- <Transform> inside <Text> (paint pass limitation)
- multi-line transform (transform nodes not yoga carriers)
- text/box nesting validation (no runtime validation yet)
- complex Static rerender patterns (Ink-specific API)
Also fixes wrap="hard" to use wordWrap:false so text breaks at exact
character boundaries rather than word boundaries, matching Ink behavior.

Covers inheritance, override, hex/rgb/ansi256 colors, wide chars,
emojis, fill area, fill with border/padding, border backgrounds.
