   กำลังใจ Inspired by Love — Design Tokens
   Palette (brief-mandated core + derived support colors):
     --brand-orange   #f47b30   (primary / warmth / กำลังใจ)
     --brand-white    #ffffff
     --brand-bg       #ededed
     --ink            #2b2420   (warm charcoal, not pure black)
     --ink-soft       #8a7f77   (secondary text)
     --line           #e2ddd8   (hairline borders on white cards)
     --tint           #fff3ec   (pale orange tint for highlight blocks)
     --good           #4caf7d   (success / confirmed states)
   Type:
     Display  — 'Kanit'    (Thai+Latin geometric, used for headings only)
     Body     — 'Sarabun'  (Thai+Latin text face, legible at small sizes)
   Signature element: the "heart-meter" — กำลังใจ balance rendered as a
   glowing heart fill rather than a plain number, since the product's
   whole currency is encouragement.
