/* .theme-toggle — styles for src/lib/expand.mjs's `x-theme-toggle`, and the
   same markup x-header embeds via its `theme-toggle` boolAttr (themeToggleHtml()
   is the single source of the HTML; this is the single source of how it
   looks). Load AFTER tokens.css. See public/components/README.md for load
   order and the split rationale.

   Ported from design/auto-microsite-page.dc.html and
   design/apricotter-homepage.dc.html's day/night dial — both design comps
   had this animated toggle; the real site had a plain text button instead,
   because nothing forced a reconciliation between the two (see
   features/component-passthrough-gaps.md's sibling finding on the same
   design/code drift, and .claude/skills/sync-design-components for the
   process fix). This file is what closes that specific gap.

   THE ANIMATION, for whoever edits this next: .theme-toggle__sky rotates
   180deg on theme change, swinging the sun out of view and the moon into
   it. Each orb's OWN inner .theme-toggle__orb-icon counter-rotates at the
   same time, so the icon itself stays upright instead of appearing to flip
   upside down as it swings around the sky's rotation. The moon's icon
   starts pre-rotated 180deg for exactly this reason — after the sky's own
   180deg flip, the two rotations cancel and the moon lands upright. */
