/* ToolsWorld design system.
 *
 * Four materials, each with one job:
 *  - Material Design 3 gives the structure: type scale, shape scale, elevation,
 *    state layers, ripple feedback, top app bar, snackbar.
 *  - Glass is for surfaces that float over content: header, menus, search, the
 *    tool panel and article cards. Real blur only where something moves beneath.
 *  - Neumorphism is for controls you touch: inputs are carved into the surface,
 *    buttons and switches are raised out of it, and press back in.
 *  - Clay is for friendly objects: icon tiles, tool cards, stat chips and step
 *    numbers are soft, inflated shapes with inner light.
 * The base rules come first; the "Design layer" at the end applies the four
 * materials to every component. Tools only use the class names in the UI kit.
