/**
 * CSS variable architecture:
 *
 * The root owns four variables so every part of the tile stays in proportion
 * and stays overridable from a single `className`:
 *
 *   --icon-tile-size       tile width/height
 *   --icon-tile-icon-size  glyph size applied to child svgs
 *   --icon-tile-radius     corner radius (also drives the nested inner card)
 *   --icon-tile-inset      gap between the outer ring and the inner card
 *
 * The `frame` and `soft` variants paint their inner card with an `::after`
 * pseudo element instead of a wrapper node. `isolate` makes the root a stacking
 * context, so the negative z-index pseudo paints above the root background but
 * below the in-flow icon - no extra DOM, and `render` composition keeps working.
 *
 * Tone: `soft` and `solid` derive every fill and border from `currentColor`, so
 * a single text color class (e.g. `text-success`) retints the whole tile. They
 * default to `text-primary`; override it to recolor without touching internals.
