   UXKB — design tokens
   Colours taken from the official CI manual (UXKB Corporate Identity.jpg):
     Primary   PANTONE 7739 C  deep green
     Secondary PANTONE 7506 C  cream
     Beige     PANTONE 4685 C
     Deep grey PANTONE 425 C

   Type: read off the live Canva design, NOT the CI manual. The manual specifies
   Montserrat + Noto Sans/Serif KR, but the actual design loads:
     - Nanum Gothic   -> every Korean string (headings, body, cards, CTA)
     - TT Ramillas    -> the language switcher links only
     - TT Interphases -> loaded by Canva but not used in the design
   (Confirmed via the font file URLs Canva serves; its CSS family names are
   obfuscated, e.g. YAFdJhcKBrg_0 = NanumGothic-Regular.)

   Nanum Gothic is OFL and served from Google Fonts — safe to use.
   TT Ramillas is a commercial TypeType face licensed for use *inside Canva*;
   we cannot self-host it, so --f-serif is a substitute. See README.
