 * SOFTFORM  /  Material system 1.0
 * One light source. Three surfaces. A common, quiet depth.
 * Independent CSS primitives — no framework and no external fonts.
 *
 * Surface  .sf-surface   matte, softly raised
 * Lens     .sf-lens      translucent, directional highlights
 * Well     .sf-inset     recessed into its parent
 *
 * Add .sf-tone-blue / .sf-tone-warm / .sf-tone-pink to a surface
 * to switch its contextual ink, well shadows and glass material.
