/* Simon — MeritChart assistant widget.
   Brand: navy #0F2A44, white, paper #FAF7F0, border #E5DDC9;
   gold #B8860B / #E8C766 appear ONLY as micro-accents (the mark's
   bars, focus rings, the header subtitle) per the design system.
   Self-contained: no dependency on page CSS variables.
   z-index 80: above the mobile sticky CTA bar (50) and the sticky
   nav, below any modal, so checkout always covers Simon, never
   the reverse. */
/* Mobile scroll lock (sibling-Simon lesson): while the panel is
   open, JS pins <body> with position:fixed at the pre-open scroll
   offset and restores it exactly on close, so the page behind
   cannot move; overscroll-behavior stops residual chaining. */
