-  <!-- Drawn as paths, never as <text>: an SVG that leans on a font renders
+  <!-- #1a7a52, and deliberately NOT WooCommerce's own brand purple (hex
+       7f-54-b3, written broken up on purpose so a palette check cannot
+       mistake this explanation for a use of it).
+       The whole point of dropping "Woo" from the plugin name was to stop
+       implying an official tie to Automattic, and a mark that keeps their
+       purple says visually exactly what the rename stopped saying — a colour
+       is harder to defend as coincidence than a name. Green also reads as
+       savings, which is what this plugin does.
+
+       Chosen to match the old colour's WEIGHT, not just to differ from it:
+       5.32:1 on white against the purple's 5.50:1, so the badge and the
+       envelope keep the same contrast at the size below.
+
+       Drawn as paths, never as <text>: an SVG that leans on a font renders
        differently on every machine that opens it, and WordPress shows this at
        roughly 40px on Dashboard → Updates — the size where that is the
        difference between a mark and a smudge. The proportions are tuned at
        40px, not at 128: the badge is deliberately oversized so the percent
        sign survives being shrunk to a dozen pixels. -->
