   Calendly popup
   Calendly injects this overlay into our page, so its chrome —
   backdrop, card, close button, spinner — is ours to style.
   The booking form itself lives in a cross-origin iframe and is
   themed with the colour params in script.js instead.
   Loaded after widget.css, so equal-specificity overrides win.

   RULE: never set position/transform/top/left/width/height on
   .calendly-popup. Calendly centres that element with left:50% +
   translate(-50%,-50%), so overriding either one throws it off-centre.
   `display:flex` on it is safe — it lays out the children, not the box.
