/* Reusable toggle switch */
/* ====================== */
/*
  A self-contained, theme-aware switch — no Bootstrap classes required. A bare
  checkbox is restyled into a track + knob that fills with the theme accent when
  on. Markup:

    <div class="pg-switch">
      <input class="pg-switch__input" type="checkbox" id="…">
      <label class="pg-switch__label" for="…">Label</label>
    </div>

  The label renders to the left of the switch regardless of source order, and the
  whole row stretches to fill its container (label left, switch right).

  Modifier:
    .pg-switch--sm   slightly smaller track/knob with a wider label gap
