Narrow the sunglasses and fix portrait-type parsing

Move the hinges to +/-0.075 (0.035 box), arms to +/-0.098, and lenses to a
0.024 m radius while keeping the lens plane in front of the eyes. Rebuild the
GLB and AO; fit now measures 0.202 m total width (0.64x head). capture_realism
now parses the documented --portrait-type option instead of ignoring it.
Python tooling 87/87; headless 228/228.
