  Version history (newest first)
  v1.5.0  18.10.2026  Back-to-top button stays to the very bottom; the footer link hides when the button works;
                      more room under the footer wordmark on small screens.
  v1.4.0  18.10.2026  Floating back-to-top button with a scroll progress ring.
  v1.3.0  18.10.2026  Custom cursor (coral dot) removed; the normal system cursor is back.
  v1.2.0  14.10.2026  Footer columns flow with flex, so hidden columns leave no gap.
  v1.1.0  14.10.2026  Author photo: fills the frame, slightly darkened, soft vignette.
  v1.0.0  14.10.2026  First release: brand tokens, opening animation, side rail, sections 01 to 08,
                      footer, custom cursor, reduced-motion and mobile fallbacks.
