/* ════════════════════════════════════════════════════════════════
   Lesson tutoring CTA  (.lcta)  —  "ticket stub" treatment
   Single source of truth for the "Book a free session" block injected
   into every lesson & worksheet by qa/phase4-inject-cta.js.
   Loaded via an absolute path (/assets/css/lesson-cta.css) so it works
   regardless of how deep the page sits or which CSS stack it uses.

   The markup is fixed (icon span + body + link); the look is driven
   entirely from here. Treatment: a printed ticket — solid plum stub on
   the left holding a line-art cap mark, a dashed perforation seam, warm
   cream body, and a flat "admit one"-style bordered action. Deliberately
   avoids the pastel-gradient + rounded-icon-tile + pill-with-arrow combo.
   Palette: warm cream + plum tokens from quiz-engine.css.
