   LARINA — design system
   ---------------------------------------------------------------------
   Every colour here is taken from the designer logo files, and the roles
   follow how the mark itself is built: the lotus has a ROSE-GOLD OUTLINE
   framing a rose chevron over a navy chevron. So on this site rose-gold
   is a *frame* colour — hairlines, borders, rules — and never carries
   text (it measures 1.96:1 on the ground, far below the 4.5:1 floor).
   Navy carries structure, rose carries action.

   Contrast, measured against --ground (#FDFBF9):
     --ink        #0B2545   15.4:1   headings + body
     --ink-soft   #4A4038    9.8:1   secondary body
     --ink-mute   #6B5D52    6.1:1   captions, meta
     --accent     #C0294F    5.5:1   links, CTAs, small accent text
     --accent-hi  #D8486C    4.0:1   LARGE/BOLD display text only (>=18pt)
     --gold       #E4A89C    1.96:1  DECORATIVE ONLY — never text
