/* =============================================================================
   PlanWatch audience switch: "For homes | For trades"
   Direction B, "Site Plan". Built to sit inside B's floating pill header.

   Markup comes from render.js (or audience-switch.ejs, byte-identical). It works
   with no JavaScript: the side you are on is baked into the markup and the thumb
   is placed by CSS. audience-switch.js adds the motion: the hammer and house
   sequences, press feedback, the idle hint and the arrival hello.

   Rules this file keeps:
   - Motion is transform and opacity only. Nothing changes the page's layout; in Chromium the moving SVG
     parts re-lay-out only their own 30 px icon, about 0.1 ms a frame (proof/report.json).
   - prefers-reduced-motion: static icons, opacity fades only.
   - Uses B's tokens (tokens.css) when the page has them; works without them.
