Add @chenglou/pretext dependency and fitTextFontSize() utility that uses canvas measureText to compute the largest font size that fits text within a given width. Replaces character-count heuristics with actual font-aware measurement. - New fitTextFontSize() in @hyperframes/core/text, exposed on window.__hyperframes - Generalized for all text elements (captions, titles, etc.), not just captions - Unit tests (mocked pretext) + browser integration test (real Chromium canvas) - Updated captions skill docs with usage, exit guarantee, and self-lint patterns Co-authored-by: James <james.russo@heygen.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
