/* Spring Tree Service Pros — base stylesheet
   Single static stylesheet, no build step, no external font/JS dependency.

   Palette: aubergine chrome with a chartreuse highlight, assigned before the
   build. The rationale is recorded outside the web root.

   Contrast, computed rather than eyeballed (WCAG AA needs 4.5:1):
     --inner-script-c on --steady-field ................................ 16.92:1
     --spire-quiet on --steady-field .............................. 6.98:1
     white on --heartwood (chrome) ................ 14.90:1
     white on --burl (buttons, accent) ............ 9.75:1
     white on --burl-deep (hover, footer) ......... 12.97:1
     --burl on --steady-field (links, labels) ............... 9.08:1
     --burl on white .............................. 9.75:1
     nav link / hero lead (#e6dcef) on chrome ..... 11.25:1
     brand mark (--catkin) on chrome .............. 12.17:1
     ink on --catkin (tier tags) .................. 14.85:1
     footer text (#c4b3d4) on --burl-deep ......... 6.64:1
     success text (#4a2769) on #efe7f5 ............ 9.76:1
     error text (#b3261e) on #fdecea .............. 5.72:1
   --cambium (#7a52a0) is the light end of the hero gradient and a card tint
   only; white on it is 5.93:1 but it is never used behind body text.
   --catkin is small-area only: tags and the brand mark, never large fills.
