/* ===================================================================
   A2Z embeddable widgets - the stylesheet every /embed/w/{slug} frame
   loads. One file, no web fonts, no images, no framework.

   Theme: <html data-theme="light|dark|auto">. "auto" follows the
   visitor's OS through prefers-color-scheme. The accent colour arrives
   as --e-accent set through the CSSOM by a2z-embed-core.js (the frame's
   CSP has no 'unsafe-inline' for styles, so it can never be a style
   attribute in the markup).

   Options map to attributes on <html>:
     data-compact="1"  tighter spacing, smaller type
     data-border="0"   no outer border / shadow
     data-title="0"    header hidden (set by the server, not here)
   and --e-radius (0-24px) through the CSSOM.
