+    Phokus app mark — a camera iris.
+    The hexagon in the middle is the lens OPENING; each blade edge sweeps from a
+    corner of the opening out to the rim, all leaning the same way (the pinwheel).
+
+    Tuning knobs (edit and re-open in any browser/Figma):
+      * opening roundness  -> the "52" radius in the opening <path> arcs.
+          smaller (toward 30) = rounder/softer hole; larger (toward 90) = flatter, sharper.
+      * blade curve         -> the "110" radius in each blade <path>.
+          smaller = more pronounced curve; larger = straighter blade.
+      * blade sweep amount  -> the +40deg baked into the blade endpoint (70.71,-84.27).
+      * curve DIRECTION     -> the final flag in each "A r r 0 0 X" command (0<->1 flips the bow).
+      * weight              -> stroke-width on the <g>.
+      * color               -> stroke on the <g>; swap "#e9e9ec" for currentColor to inherit.
+    A brand-accent focal dot is provided at the bottom (commented out).
