   Minimal - Design System v4
   Loaded last: redefines the tokens from style.css/v2.css and restyles the shell.

   Principles
   · Warm paper in light, deep ink in dark - never pure #fff/#000.
   · Colour is meaning. The only saturated things on screen are availability
     rings and post-type accents. Everything else is greyscale.
   · Motion is spring-based and short (160-320ms). It confirms, never entertains.
   · Every interactive target is ≥44px on touch.
