/**
 * Shared custom CSS for "BuyLens" static frontend.
 * Tailwind (via CDN) handles utility classes; this file holds everything
 * Tailwind can't express directly: glassmorphism, animations, gradients,
 * and the light/dark theme-transition wipe.
 *
 * Light mode here is a deliberate refinement over a literal 1:1 inversion
 * of the dark mode file the Stitch export shipped with -- dark-tuned
 * translucent panels tend to look washed out and shadow-less on a light
 * background if you just flip the opacity. Light mode uses slightly more
 * opaque surfaces, a crisper 1px border, and soft multi-layer "ambient"
 * shadows (per DESIGN.md's elevation guidance) so cards read as physically
 * separated from the page rather than flat rectangles.
