/* The launcher's look: the AI Lessons site's top bar, footer and tokens (site.css), a purple hero, and the tool cards.
   DM Sans, deep royal purple for structure, warm gold for emphasis, white page, #F2EFFA as the only tint.
   No images but the AISA marks: the glows, the dot grid and the pictures are CSS and inline SVG. */
