/* Badges sit straight on the white footer, sized by their visible artwork (29 Oct 2026), never cropped or recoloured.
   TISC and CAUK fill their files: both are --badge-h tall. DC is wide and short: its file is .7 × (artwork .662 ×), so its area balances the CAUK square;
   its file's empty bottom strip (13 of 241 px) is let fall away so the artwork centres. The Covenant file carries its own clear zone (the crown's height,
   about 12.6% of the file on each side), so it is drawn 1.4 × (crest to COVENANT ≈ 1.04 × --badge-h) and negative margins let only that empty padding
   overlap the gap. Gaps are .36 × --badge-h, about twice the crown's height, so the Covenant keeps its clear zone.
   Pledge 1% (29 Oct 2026): the official stacked SVG's artwork fills its viewBox (308.38 × 320.16), so like TISC and CAUK it is --badge-h tall.
   Row = 6.378 × --badge-h wide (DC 1.452, TISC .803, CAUK 1, Pledge .963, Covenant .720, four gaps 1.44). */
