/* The PCB canvas renders behind these two — a solid-only outline
   lets the circuit traces show through and reads as visual noise.
   A translucent scrim (not a brand-rule "filled button") separates
   them from the background without adding color.
   No backdrop-filter: blurring a live-animating canvas behind it is
   a well-known trigger for stutter/scaling glitches on mobile
   Safari/Chrome during scroll — a plain solid-ish scrim gets the
   same legibility without touching the compositor that hard. */
