What does guizang-ppt-skill do?
Generate a horizontal swipe web presentation (single HTML file) with WebGL backgrounds, chapter dividers, data billboards, image grids, and other templates. Two styles are available: ① "E-magazine × E-ink" (serif font + fluid background + warm colors) ② "Swiss International Style" (sans-serif + grid dot pattern + IKB / lemon yellow / lemon green / safety orange highlights). Use this skill when a user needs to create shareable / slideshow / launch-style web presentations, or mentions "magazine-style PPT", "Swiss-style PPT", "Swiss Style", or "horizontal swipe deck".
