/* inherit-brain demo site. One stylesheet, custom properties, no build step.
   Colour rule: --accent belongs to inherit-brain (A5) only. Every other arm is drawn in --mark (neutral grey).
   Links, buttons, tabs and focus rings use ink, never the accent.
   Shape rule: one radius (--r, 6px) for every container, control and chip; data marks (dots) are circles. */
