-    Agendula launcher icon foreground — PLACEHOLDER.
+    Agendula launcher icon foreground.
 
-    A simple rounded check mark inside the 108dp adaptive-icon canvas
-    (72dp safe zone). Deliberately not Calendula's calendar mark, so the two
-    apps never look alike. Replace with real branding (a stylized agendula)
-    when the design lands — see docs/PLAN.md §9.
+    Converted from design/icon/agendula_icon.svg (512x512 viewport): a rounded
+    line-art task card with a check mark, plus a small Calendula bloom badge in
+    the bottom-right corner — the sibling of Calendula's calendar mark.
+
+    Strokes render in off-white (#FAF6F0) over the plum background drawable
+    (drawable/ic_launcher_background.xml = @color/ic_launcher_background, the
+    hue-rotated counterpart of Calendula's slate). The same vector fills the
+    <monochrome> slot so Android 13+ themed-icon launchers can recolour it.
+
+    Centering / scale:
+    - The artwork's visual centre sits at (269, 256) in the 512 viewport.
+    - Pivot there, scale 0.66 (matching Calendula's ~2.8dp stroke weight and
+      generous padding), then translate (-13, 0) onto the 512 canvas centre.
