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.

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.

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.

- Remove yoga setOverflow call — Ink only clips visually in paint,
not at the yoga layout level. Calling setOverflow(HIDDEN) prevented
nodes from expanding, diverging from Ink's behavior.
- Fix AlignContent type to exclude baseline (not valid for align-content
in CSS/Yoga, and Ink doesn't allow it).
- Keep border background fallback to backgroundColor — Ink achieves
the same visual result via background fill underneath borders.

The frame writer initialized lastFrame to "" and also reset it to ""
on clear(). Since commit() calls clear() then write(), any component
that painted to an empty string (e.g. Transform with no children, or
a component returning null after unmounting children) would be
deduplicated against the cleared state and never emitted.
Use null as the sentinel for "no previous frame" so the first write
after a clear always goes through, even when the frame is empty.
Fixes: Transform with null/undefined children tests
Fixes: Focus unmount crash tests (stale frame persisted)

Previously Output.get() only used the last clip rect (clips.at(-1)),
which meant an inner overflow:hidden box wider than its outer ancestor
could effectively loosen the outer clip. Now all active clips are
intersected via reduce, and writes are skipped entirely when the
intersection is empty.

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).

Ink's <Text> sets flexShrink: 1 by default so text nodes shrink when
they overflow their container in no-wrap flex rows. Without this,
vue-tui's text nodes had flexShrink=0 (yoga default) and would never
shrink, causing overflow tests to fail.
Also ports Ink's measureTextNode guard: when yoga asks if text can fit
in a sub-1px space during shrink calculations, return the natural
dimensions to prevent text from wrapping to infinite height.

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.

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.

Translates flex, direction, wrap, align, justify, gap, padding,
margin, width-height, position, display, and overflow tests from
Ink. Adds trimLines mode and trailing-newline strip to test helper.
Fixes Box type for alignContent (space-between/around/evenly) and
alignSelf (stretch/baseline).
21 tests fail due to behavioral differences (overflow clipping,
percentage dimensions, relative position offsets, align-content
space-* variants). These represent real gaps to investigate.

Adds borderTopDimColor/borderBottomDimColor/borderLeftDimColor/
borderRightDimColor and borderBackgroundColor with per-side variants.
Refactors drawBorder to use per-edge colorizers that respect
edge-specific color, dim, and background overrides.

Hard wrap breaks text at exact width boundaries without respecting
word boundaries. Uses wrap-ansi with { hard: true, trim: false }.

Adds 9 new Box props backed by yoga-layout: maxWidth, maxHeight,
aspectRatio, alignContent, position, top, right, bottom, left.
Also adds baseline alignment support. Includes reset semantics
for props that Ink tests exercise clearing on rerender.

Ink uses 'ansi256(N)' while vue-tui only parsed 'ansi(N)'.
Both now work. Needed for Ink test migration.

Removes trimEnd() from the paint grid output. The test helper's
trimFrame() still handles cosmetic trimming for lastFrame(), so
existing tests are unaffected. This enables layout tests to assert
exact widths via lastFrame({ raw: true }).

TUI apps should suppress terminal echo to prevent keystroke pollution
in the rendered UI. Raw mode is now on by default (matching Bubbletea,
Textual, Ratatui), with exitOnCtrlC also defaulting to true.
Pass rawMode: false to mount() for pure-output CLI tools that don't
need input suppression.

- Wrap each text line with applyChalk(bgProps) after wrapText so
background color is reapplied on every wrapped line (wrap-ansi
doesn't carry ANSI state across line breaks)
- Add wrapped-text backgroundColor regression test
- Fix typo: color=" cyan" → color="cyan" in example
- Add FORCE_COLOR=3 debugging tip to AGENTS.md

- Fill background inside border area only (not under border chars)
so border placeLine doesn't overwrite background ANSI codes
- Pad text lines to full layout width when inheritedBg is set
so background extends past text content to fill the row

Root causes:
- drawBorder wrote plain characters, overwriting fillBackground's ANSI codes
- renderTextWithInlineStyles spread node.props over inherited bg, but
undefined props from Vue clobbered the inherited backgroundColor
- Child text nodes did not inherit backgroundColor from parent Box
Fixes:
- drawBorder applies backgroundColor (and borderColor) to border chars
- Filter out undefined props before merging in renderTextWithInlineStyles
- Pass inheritedBg through the paint tree to text nodes

Static content is rendered via paintIsolated (separate channel), but its
yoga node was still participating in the dynamic frame layout calculation,
adding blank lines equal to the Static content height between the last
Static item and the dynamic content below.
Setting display:none on the Static yoga node removes it from the dynamic
layout. paintIsolated is unaffected — it reparents children into a
temporary yoga tree.
flushStatic() writes directly to stdout, but log-update tracks cursor
position for in-place re-rendering. Without clearing log-update first,
the static content gets overwritten when the dynamic frame re-renders.
Adds a regression test that verifies the clear sequence appears before
static content in non-debug mode.
- Bump all packages to 0.0.1
- Add publishConfig.access: public to @vue-tui/cli
- Disable tsgo for dts generation (missing native-preview dep)
