   R&B TEA — US Franchise Site
   Design: warm hospitality x premium editorial
   Palette (all pairs verified WCAG 2.1 AA via contrast_check.py):
     --cream         #FAF5EC  page background (13.8:1 with ink)
     --cream-deep    #F2EADA  alternate section background
     --card          #FFFCF6  card / surface
     --ink           #2B2620  primary text (warm near-black charcoal)
     --ink-soft      #57503F  secondary text (7.4:1 on cream)
     --caption       #6B6350  muted text (5.5:1 on cream)
     --accent        #B45309  deep amber / burnt orange (4.62:1 on cream)
     --accent-deep   #92400E  deeper amber (hover / eyebrows)
     --accent-bright #E8A33D  amber for dark backgrounds only (4.67:1 on teal-dark)
     --teal          #115E59  deep teal secondary (6.98:1 on cream)
     --teal-dark     #0C4A47  dark section / footer background
     --line          #8A7A5F  hairline borders (>=3.84:1 against surfaces)
   Colorblind-safe: amber/teal/charcoal/cream scheme survives protanopia,
   deuteranopia and tritanopia; no red/green pairs; meaning is never
   conveyed by color alone (icons + labels + numbers everywhere).
