   INKLINE · Holista sketch board   (needs tokens.css; DESIGN.md §24, SKETCH.md)
   Flat ink or paper, hairlines, ONE marker colour (the recording dot, Holista's pen, snap guides, the spoken word), no gradients, no blur,
   springs (--ik-press / --ik-soft), shapes not colours. The board sets its own ground, so it follows `theme: 'ink' | 'paper'` and not the page.
