letter-spacing.md

npm:tegaki	minor

Infer and apply CSS letter-spacing

The renderer now reads letter-spacing from the container's computed style — alongside font-size, line-height, and color — and applies it to the animated strokes, re-measuring when it changes. Spacing is inserted between clusters in the shaper pen-walk (matching the browser exactly for Latin, CJK, and non-cursive RTL like Hebrew) and picked up automatically from the DOM-measured offsets on the char-keyed fallback path, so line wrapping, glyph positions, and the drawn text stay in sync. The headless textToSvg export gained a matching letterSpacing option.

Fix the React TegakiRenderer ref handle on React 18

TegakiRenderer exposed its imperative handle via React 19's ref-as-prop, which React 18 silently drops (ref is not a prop), leaving the ref null despite the declared react: >=18 support. It now uses forwardRef, so the { engine, element } handle works on both React 18 and 19 (the generic component API is preserved).

npm:tegaki	patch

Fix doubled ghost text when exporting through DOM rasterizers

The DOM text overlay (kept for selection, accessibility and layout measurement) was hidden only with -webkit-text-fill-color: transparent. DOM-to-image/video rasterizers that don't implement that non-standard property — Editframe, html-to-image, Satori, headless-screenshot pipelines — repainted the overlay text in the inherited color and a default font, doubled on top of the canvas handwriting. It is now hidden with the standard color: transparent, which those exporters honor. (In editable mode the caret follows currentColor, so it is no longer independently visible — an accepted trade-off for correct exports.)
