   LethalPath — design system

   Tokens extracted from real premium developer-tool systems (Raycast's
   published design tokens, read as DATA via Bright Data) and adapted. The
   point of the exercise: remove the tells that make a site read as machine-made.

   What was wrong before, and what changed:
     - every heading at 700          -> 500/600, display gets tighter tracking
     - uniform 12px radius everywhere -> a real scale (4/6/8/10/14/9999)
     - one border colour              -> hairline / soft / strong tiers
     - 78px on every section          -> 88px desktop rhythm, varied where it reads better
     - accent colour on all chrome    -> monochrome chrome; colour ONLY where it
                                         carries meaning (the four legs + the fix)
     - -0.02em on body text          -> tracking scales with size; body gets none
     - four identical cards in a grid -> asymmetric splits and a real hierarchy

   Accessibility (measured, not assumed). Ratios are against --canvas; the
   parenthetical is the worst surface each colour is actually painted on.
     --ink        #F4F4F6 on --canvas   18.24:1  AAA   (16.03:1 on --surface-3)
     --body       #CDCDCD on --canvas   12.60:1  AAA   (11.07:1 on --surface-3)
     --mute       #A9A9AB on --canvas    8.54:1  AAA   ( 7.50:1 on --surface-3)
     --ash        #A3A4A6 on --canvas    8.03:1  AAA   ( 7.51:1 on a #121212 node rect)
     --untrusted  #FFC533 on --canvas   12.68:1  AAA   (11.14:1 on --surface-3)
     --private    #B69EFB on --canvas    8.85:1  AAA   ( 7.77:1 on --surface-3)
     --sink       #57C1FF on --canvas   10.00:1  AAA   ( 8.78:1 on --surface-3)
     --danger     #FF8A8A on --canvas    8.83:1  AAA   ( 7.76:1 on --surface-3)
     --safe       #59D499 on --canvas   10.78:1  AAA   ( 9.48:1 on --surface-3)
     Status chips (.tag-*) clear 7:1 on their tint over --surface-2; the worst
     is .tag-pr at 7.23:1. White CTA: #000000 on #FFFFFF 21.00:1 AAA.
