/* ============================================================================
   THE CURRENT — the immense main-site direction of The Luminous Circuit
   v3/styles.css
   ----------------------------------------------------------------------------
   One continuous field of living light (WebGL, hand-written, zero-dep) runs
   beneath a monumental typographic liturgy. Laws:
   1. Awe, never urgency. Nothing counts down, nothing pushes.
   2. The default stylesheet is the finished page: no-JS, reduced-motion,
      screen readers, and print receive the complete, beautiful document.
      All choreography sits behind prefers-reduced-motion: no-preference,
      html[data-anim-ready], and the visitor's own Be-still toggle.
   3. Doctrine verbatim; notices plain; the boundary is always on the page.
