1.0.3 - 2026-06-02

Dynamic Formatting in updateTable: Added support for inline cell styling (color fill fill, text alignment align, and fontSize) directly on cell objects passed to updateTable.
Comprehensive Tailwind Site: Overhauled doc builder script to generate a premium Tailwind CSS documentation portal with clientside search, clipboard copying, sitemap.xml, robots.txt, and Schema.org metadata.

XML Element Ordering: Enforced strict schema-valid element sequence (a:pPr -> runs -> a:endParaRPr) in slide table cell paragraphs. This resolves the bug where split cells inheriting from template merged cells had their text runs ignored by PowerPoint's XML compiler.
Template Style Inheritance: Fixed a bug in updateTable where cloned rows always copied the first data row (trs[1]). The engine now correctly inherits formatting, alignment, and fill styles from matching indices in the template (trs[i]) when available.

Table Cell Merging & Unmerging Engine: Fully implemented horizontal cell spans (gridSpan, hMerge), vertical cell spans (rowSpan, vMerge), and rectangular block merges.
PowerPoint Repair Protection: Implemented unique 32-bit unsigned rowId generation inside <a16:rowId> XML tags for all cloned and inserted rows, eliminating PowerPoint's "Repair Mode" error prompts.
Merge Integrations: Integrated template-driven merges (merge configs array and cell-level colSpan/rowSpan) inside the main updateTable orchestrator.
Integration Test Suite: Added a comprehensive merge test script under tests/integration/PPTXMerge.test.js.

CommonJS Target Conversion: Converted the source code modules compilation and packaging layout from pure ES Modules (ESM) to CommonJS (CJS) to ensure compatibility with standard Node.js deployment, packaging, and edge runtime environments.
