   Unmild Designer — marketing site
   Design system, documented.

   COLOR — anchored on H=247 degrees (the app's own violet UI accent). The
   app's three real UI colors -- violet 247, PCB green 144, copper 32 --
   sit 103-112 degrees apart, a loose triadic relationship. Every neutral
   in this file is the same 247 hue at low saturation (a tinted-black, not
   true gray), so panels, borders and text all sit in one coherent
   temperature. Accent ramps are single hue/saturation pairs stepped only
   by lightness.

   TYPE — modular scale, base 18px, ratio 1.25 (major third). Each heading
   size is a fluid clamp() interpolated between the scale step at a 400px
   viewport and the step two above it at 1440px, using the standard fluid-
   type formula (slope = delta-px / delta-vw). Nothing here is eyeballed.

   SPACE — 8pt grid (4px half-step at the bottom only): 4 8 12 16 24 32 48
   64 96 128.
