/* ═══ ENGRAVING STUDY ═══ 27 Oct 2026. Real engraved star plates in
   place of the drawn ring instruments, and no glowing orbs. The plates
   are public domain (Wikimedia Commons): Johann Bayer's Uranometria
   (1603) for Sagittarius and Scorpius, her Sun and her stellium, and
   Christiaan Huygens' Systema Saturnium (1659) for Saturn. Each lives
   in shared/images/engravings/ as an ink-only stencil, so the lines
   take --mt-ink and turn with the sky. Linked after sky-clock.css on
   the home page only; add ?before to the address to switch it off.
   Deleting this file and its <link> restores the page exactly. ═══ */
