/**
 * MASTERKA — Footer (hybrid 1 × 4 × 8)
 * Big CTA + numbered links (inline on desktop, a list on mobile) + bottom bar,
 * cursor dot grid, orange glow, grain and an entrance animation (driven by assets/js/footer.js).
 *
 * Performance: the glow moves with a transform (compositor only), the dot mask is updated
 * on its own layer at most once per frame and only while the pointer is over the footer,
 * and the grain is baked into the background (no blend mode over animated content).
 *
 * Rounded corners: the dark panel (.mf-body) carries the radius, the outer section (.mf)
 * is painted with the colour of the section above (--mf-corner, set by footer.js),
 * so the corners read correctly in every state, including while the panel scales in.
