/* The Select Period window, laid out as the reference lays it out.
 *
 * Three list columns of equal width with centred captions, rows as short filled bars with a
 * leading check mark and a hairline gap between them, an options panel to the right, the
 * instrument line bottom-right of that panel, Go To Date bottom-left and Apply & Reload
 * bottom-right. Every colour resolves through the theme tokens so the window changes with the
 * theme like everything else; the geometry is the reference's.
 *
 * This sheet owns every .pp-* rule. It used to be defined in three places by two parallel
 * restyles; one sheet, linked last, is the only way that stays true.
