Summary

• apply OOXML default text body insets when bodyPr omits inset attributes
• improve empty txBody handling so styled, large placeholders can be parsed as visual shapes
• add HSL-based luminance transform support for scheme colors and scoped alpha handling for shape fill/stroke colors
• preserve custom geometry path command order and parse path metadata into shape model
• update fixture snapshots and tests to lock in new parser behavior

Validation

• pnpm run fixtures:generate
• pnpm run verify
• pnpm run pack:check
• VISUAL_CASES=slop-sample pnpm run test:visual

Notes

• focused visual validation keeps slop-sample slide 11 around diffRatio 0.1018 while avoiding broader regressions from more aggressive custom-geometry rendering experiments
