   aura-compare.css  |  AURA Compare Widget — Doctor Advisor / Teal Theme
   TerraLeap · UpLeap Technologies
   Companion to aura-learn.css — same architecture, different behavior:
   NO persistent launcher icon. Nothing exists on screen until
   terraleap-aura-trigger.js calls window.AuraCompare.open() — the first
   time after the visitor goes idle on a course/exam page, and roughly
   every 3 minutes after that (see that file's repeat-scheduling notes).
   A doctor-with-stethoscope avatar drops in top-right with a plain
   yes/no question; only on "yes" does the comparison panel open, in
   that same top-right spot. See aura-compare.js for the public API
   (open/close) and the flow between advisor → panel.
   ============================================================ */

/* ── Advisor avatar — a complete standing doctor (not a cropped bust),
   drops in top-right (same corner the panel docks in), asks a yes/no
   question via the card below it. No backdrop: this is meant to read
   as a lightweight notification, not a takeover — especially since it
   may reappear every few minutes.

   Real 3D, not just a flat bob: .ac-advisor-badge establishes the
   `perspective`; .ac-advisor-3d is a `preserve-3d` group that continuously
   tilts (rotateY/rotateX); its two child SVGs (coat/legs behind, head +
   free-hanging arms + stethoscope in front) sit at different translateZ
   depths, so the tilt visibly separates them — a real parallax, not a
   flat card spinning. No circular crop this time — it's a free-standing
   silhouette with its own ground shadow baked into the artwork. ── */
