   Agromigo Greenhouse Impact Calculator — Stylesheet
   Version: 7.0.0
   =============================================================================

   ARCHITECTURE
   ─────────────
   This file styles only the .agc-calculator scope. It intentionally does NOT
   redeclare rules already provided by the global WordPress theme stylesheet
   (ui-elements.css). Specifically:

     • input[type="text"], input[type="email"], input[type="password"]
       → border, padding, border-radius, focus state all inherited from global

   Only input[type="number"] and <select> are declared here because they are
   not covered by the global stylesheet.

   THEME TOKENS (required in global stylesheet)
   ─────────────────────────────────────────────
     --houtskool     Dark charcoal — primary text, borders, dark surfaces
     --kiem          Lime/yellow-green — brand accent, focus, highlights
     --salie         Muted sage — used as mobile card tint background
     --border-radius Shared corner radius
     --border-width  Shared border stroke width
     --font-size     Base font size
     --gutter        Horizontal/gap spacing unit
     --padding       Card internal padding
     --bg-color      Page/card background (optional, falls back to #fff)
