/* ── Glass-jar effect ─────────────────────────────────────────────────────
   The canvas renders fruit; the wrapper hosts a multi-layer glass overlay
   on TOP (via ::before/::after + inset box-shadow). Effects, top → bottom:
     1. Outer drop shadow — "weight" of a heavy glass jar
     2. Inner rim highlight — thin bright edge around the opening
     3. Top rim band — slightly darker line at the very top (jar mouth)
     4. Left soft highlight streak (wide) — main glass reflection
     5. Right thin highlight streak — secondary reflection
     6. Inner vignette + bottom shadow — depth + accumulated weight at base
   pointer-events: none on overlays so canvas still receives clicks. */
