/* MagickMirror -- magickmirror.net
 *
 * Brand: the dark side of the glass. John Dee's scrying mirror was Aztec
 * obsidian, and that is the ground here: a near-black with a green cast, the
 * colour volcanic glass actually is. The ink is silvered sage, after the tin
 * and silver that backed a mirror before aluminium, tinted cool by the iron in
 * the glass. Garnet is the one warm note and it is reserved for the SOURCE
 * side of the product -- the host PC, doing the work in the other room. Cool
 * is the reflection, warm is the source; garnet never decorates.
 *
 * The page is dark throughout except one band, "What it never does", which is
 * silvered. That is the commitments section, and it is the part of the glass
 * that is clear.
 *
 * Nothing here is inherited from RetroBakery. The app still carries that
 * project's warm terracotta palette and its Fraunces/Lora pairing; this site
 * is deliberately its own thing.

   the same thing arriving somewhere else, dimmer and a beat behind.
   Decorative, so it is hidden from assistive tech.

   The clip lives on the outer box and the flip on the inner one.
   `transform-origin` stays at `center`, which maps the inner box's bottom edge
   onto its top edge, so the headline's LAST line is what lands under the glass
   -- which is what a mirror returns. An origin of `top` reflects the element
