/* ISOT Member App — design system
 * Built from the ISOT identity artwork: black ground, flat palette colour, and a

 * dot is a quarter, the S two halves, the O a circle, the T a bar and a quarter.
 * So the geometry is the identity, and it is used here structurally rather than
 * as decoration: avatars are split circles, the spinner is a half, cards carry a
 * single arc corner, section marks are half-discs.

     ISOT — built from the identity artwork, not from a UI kit.
     Black ground, flat palette colour, circles and half-circles.

     Colours are the confirmed system (ISOT-Colour-System.pdf, Aug 2026):
     11 values in three hue arcs, plus the proposed greens and neutrals.
     Nothing here is off-palette. The old #EE0979 pink never was on it.
