/* Starchart Study: the Celestial skin, night first, with liquid glass, a canvas sky and
 * scroll reveals. theme/celestial.md is binding, with one recorded deviation
 * (site/LOOK.md, "Night first"):
 *
 *   :root                     the NIGHT plate (deep navy + gold): what a first visit sees
 *   :root[data-theme=light]   the DAY plate (warm parchment + brass), once the reader asks
 *
 * Both blocks declare the same token names. No hex or rgba literal outside them.
 * Every pair was measured, both plates (site/LOOK.md, "Tokens").
 * The canvas (site.js) reads its colours and numbers from these tokens too:
 *   --sky-ink     the stars' ink          --star-a / --star-r  their opacity / size multipliers
 *   --line-a/-w   constellation line alpha / width             --rose-a  the rose's ink alpha
 *   --veil-under  how much sky is erased under display text (rose included)
 *   --veil-over   how much sky is erased under body text, after everything else is drawn
