/* ----------------------------------------------------------------------
   Two bugs lived here, and they compounded. Fixed 2026-08-01.

   1. `.bill__form` and `.bill__upload` both set `display: grid`. A class
      selector beats the user-agent `[hidden] { display: none }` rule, so
      the `hidden` attribute did NOTHING — step 2 was rendered on top of
      step 1 the whole time, and vice versa.

   2. v5-base.css line 909 sets
      `.bill input[type="file"] { position: absolute; inset: 0; opacity: 0 }`
      — the original dropzone pattern, where the whole panel is one big
      invisible click-to-upload target.

   Together: an invisible full-panel file input sat over the step-1 form,
   so clicking the Name field opened the file picker instead of focusing
   the input. Every field on the form was unreachable.

   The `inset: 0` overlay is still correct for the inline dropzones on the
   Elementor pages, so the override below is scoped to the popup only.
