Issue

Text boxes larger than their actual visible content bloats canvas space

Solution

Auto-resize text boxes

Risk

Low

Checklist

Acceptance criteria met
Continuous integration build passing

Summary by CodeRabbit

New Features
- Text boxes now automatically resize to fit their content after edits and property-name changes, including rotated text boxes.
- Default text-box height adapts to the configured text style and padding.
- Larger text-boxes drawn on the canvas retain their drawn size and do not automatically resize.
Bug Fixes
- Improved text wrapping for long words, whitespace, and property chips, including breaks between complete characters.
- Corrected cursor movement at wrapped lines, word breaks, and line endings.
- Preserved trailing spaces as addressable cursor positions during navigation.

📝 Walkthrough

The authoring editor now adjusts textbox height after edits, additions with history, and property synchronization. Text wrapping supports grapheme-safe breaks for oversized text and keeps property chips atomic. Cursor movement preserves trailing whitespace positions and normalizes positions at wrapped word breaks.

Changes: Authoring text behavior

Layer / File(s)	Summary
Text wrapping and span layout `frontend/src/features/authoring/text/build.ts`, `frontend/tsconfig.json`	Shared helpers build lines and spans. Oversized non-property text can split at grapheme boundaries. Property chips remain atomic, and the TypeScript library settings include `ES2022.Intl`.
Wrapped-line cursor navigation `frontend/src/features/authoring/text/cursor.ts`	Cursor movement preserves trailing whitespace positions and normalizes positions at mid-word breaks.
Textbox autofit integration `frontend/src/features/authoring/types.ts`, `frontend/src/features/authoring/scene/operations/autofit.ts`, `frontend/src/features/authoring/scene/operations/component.ts`, `frontend/src/features/authoring/scene/operations/modifiers.ts`, `frontend/src/features/authoring/AuthoringToolPage.jsx`, `frontend/src/features/authoring/pipeline.ts`	Textbox height is measured from visual text and adjusted with top-edge anchoring and rotation-aware bounds correction. Autofit runs during edits, history-enabled additions, and property synchronization. The default textbox height uses the single-line height helper, and `pad` is exported.

Text wrapping may fail in browsers without Intl.Segmenter. Confirm supported browser coverage or provide a fallback; otherwise the change is mergeable with that bounded compatibility risk understood.

captures the previous components and routes both mutations through the shared
history operation, emitting the corresponding historyEvents update instead of
only calling setComponents(next). Preserve the existing property synchronization
and textbox fitting behavior while ensuring autosave schedules modifyScene and

- Line 176: Update generateOffsets and pushBrokenSpan so wrapping never splits
UTF-16 surrogate pairs or grapheme clusters, while retaining startIndex and
charOffsets in UTF-16 coordinates. Ensure the ref.text.slice call used to create
each VisualSpan advances end to a valid code-point or grapheme boundary when a
character does not fit.

A text box dragged out larger than 50px on both sides is marked `autoResize: false` and keeps the size it was drawn at. Boxes created with a click still fit their text. The drawn-size threshold is now named minDrawnSize.
