/* =========================================================================
   AgnessaAI — one-page selling site
   Light "Mint + Orange" palette, balanced 60-30-10:

     60% dominant background  Pure White     #FFFFFF
     30% structure & text     Slate Tech     #0F172A   (headings, body)
                              Soft Ice       #F4F7F6   (cards, panels, insets)
     10% brand / CTA          Hyper Mint     #0DD394   (logo, CTA, AI icons)
         sales accent        Active Orange  #FF6B35   (money, won deals, closing)

   CONTRAST RULE FOR THIS PALETTE — both accent fills are light, so neither ever
   carries white text:
     ink #0F172A on mint   #0DD394 = 9.2:1      white on mint   = 1.9:1  x
     ink #0F172A on orange #FF6B35 = 6.3:1      white on orange = 2.8:1  x
   Text and icons in accent colour therefore use the darkened -soft ramps
   (#047857 mint, #C2410C orange), which clear 4.5:1 on white and on Soft Ice.

  /* ---- Button fills and the text that sits on them ----------------------
     Brand rule: text on a coloured button is WHITE. Both accent hues are light
     fills, so white text on them is below WCAG AA (mint 1.95:1, orange 2.84:1)
     — that is a deliberate brand decision here, not an oversight.
     To make white text AA-compliant without touching the brand accents used
     everywhere else (icons, tints, glows, charts), deepen ONLY these two fills:
        --fill-accent: #047857;   -> white on mint   = 5.48:1
        --fill-sales:  #C2410C;   -> white on orange = 5.18:1
     Or keep these fills and set the two -on- tokens to var(--color-ink).
     Current fills: mint #0ABE85 (white 2.41:1), orange #FF6B35 (white 2.84:1). */
