+    RD monogram. The letters are knocked out of a filled tile rather than drawn
+    on their own: at 16px the tile is what makes the icon findable in a strip of
+    tabs, where bare strokes turn to grey fuzz.
+
+    Colours are the brand accent from src/main.tsx, and they invert with the
+    theme for the same reason it does. Chrome ignores media queries inside a
+    favicon and keeps the light-theme rendering — that is fine here, because the
+    pale letters still carry the mark against a dark tab strip.
+
+    Drawn as strokes on a 64 grid so the weight is one number. Note a stroked
+    arc extends half the stroke width past its centreline; the D's bowl radius
+    is 14 from a stem at x=38, which is what keeps its outer edge inside the box.
