html-to-pptx

Convert an existing HTML slide deck into an editable .pptx that fully preserves layout, typography, colors, assets, and visual style. Use when the user gives you an HTML file containing <section> slides (or CSS-styled slide markup) and asks for a PowerPoint version that can still be edited — not a deck of screenshots. The output uses native text boxes, shapes, and images laid over pre-baked gradient backgrounds. Handles the CSS↔PPTX unit conversions (px→inches, CSS letter-spacing→charSpacing), gradient-fill limitations (bakes to PNGs), photo-to-panel transitions, Chinese typography, and the Windows/macOS PPTX→PDF→image verification loop.
