   Keleno — styles.css
   Palette:
     ink        #0B0F19  — headings, primary buttons, dark/moody sections
                           (hero, CTA banner, Vafion, footer)
     ink-soft   #4B5568  — body text on light backgrounds
     paper      #FFFFFF  — page base
     surface    #F5F6F8  — alternating section background
     line       #E4E6EB  — borders, dividers
     accent     #19A950  — primary brand accent, sampled from the Keleno
                           logo's green node — used sparingly against both
                           light and dark (ink) backgrounds
     accent-deep #127939 — accent hover / pressed
     accent-tint #ECF8F1 — pale accent fill for chips/badges
   Dark sections (.hero, .cta-banner, .vafion-section, .section--dark) share
   a faint diagonal accent streak texture (--streak) for a moody, editorial
   feel, referencing reflectionsglobal.com without copying its palette.
   Type: Inter (body/UI), IBM Plex Mono (eyebrows, tags, stat labels — the
   "engineering" accent voice)
