Landing page. Everything on the homepage lives in index.html at the project root, plain HTML with Tailwind classes. Edit the sections directly, there’s no template abstraction between you and the markup.
Other pages. About, terms, privacy, and any page you add live in _pages as Markdown files. Add a new page by dropping a .md file in that folder, it’s available at /<filename> automatically.
Colors and theme. Cookie ships with a Catppuccin palette (Latte for light mode, Mocha for dark mode), defined as CSS custom properties in assets/css/style.css. Change --bg, --surface, --text, --text-dim, --border, --accent, and --accent-text under :root and [data-theme="light"] to use a different palette, everything on the site reads color through these variables.
Icons. Phosphor Icons is loaded site-wide, so any ph-* icon class works in your HTML without adding a dependency.
Favicons. Add your own in _includes/custom-head.html. RealFaviconGenerator is a quick way to generate the full set.
