/* ===========================================================================
   OPERATOR IDENTIFICATION COLOURS
   ---------------------------------------------------------------------------
   Sampled from each operator's own official logo (africell.com, qcell.gm,
   comium.gm, gamcel.gm) on 2026-08-16. Logo use approved by the project owner
   on the basis that Pay365 already uses these marks in the Ping Money service.

   Note: Africell and QCell both sample to near-identical oranges, so the row
   colour alone cannot distinguish them — the logos do that. Africell therefore
   uses its secondary purple here to keep the rows visually separable.

   THIS IS THE ONLY PLACE THEY ARE DEFINED.

/* Operator logo in the prefix table.
   The three marks have very different aspect ratios — africell.png is a
   377x206 wordmark, comium.svg a 432x107 wordmark, qcell.png a 200x200 square.
   A square 28x28 box would squeeze the two wordmarks down to a few pixels of
   height and leave the operator names starting at different x positions. So
   the box is fixed at 76x24 for every row: `contain` scales each mark to fit
   without distortion, and `object-position: left` parks it against the left
   edge of that box, so all three names line up in the column. Keep the box
   fixed in both dimensions — that is what holds the row alignment. */
