   Secret Garden — Sabikan Recruitment LP
   Vanilla CSS. Mobile-first. Design tokens from PRD §4.
   Contrast notes (verified against #FAF6EF cream / white):
   - green-deep #2F5233 text on cream = 8.2:1 (AA/AAA) -> headings, body-dark
   - ink #2B2B26 on cream = ~11:1 -> body text
   - leaf-green #6A994E on cream = 3.1:1 -> LARGE/decorative only (never body)
   - terracotta #C1554D white text = ~4.5:1 -> large/bold button labels only
   - terracotta-deep #A8433C white text = 5.9:1 -> small pill badges (AA small)
   - line-green #06C755 with DARK ink text = 6.3:1 (white text would be 2.3, fails)
