   BEAUTY AFTER THIRTY — DESIGN SYSTEM
   Prototype:  Zine / Brutalist-editorial (LIGHT / paper-first variant — cut-out + contact-sheet)
   Palette:    paper #EFEEE9 + ink #16161A + electric teal #35D0BA (flat riso, single accent)
   Fonts:      Instrument Serif (display) / Geist (body) / Geist Mono (kicker·meta·index)
   Motion:     ~1 (CWV-first) — CSS hover/active + scroll progress only, no JS animation.
   与 strongerwithtime（同车道：Zine + Instrument Serif + 近黑+teal）明确区隔：
   strongerwithtime = DARK-first neon 健身海报；本站 = LIGHT paper 冷 riso 美妆剪贴册
   （明暗对调 + cut-out/contact-sheet 版式 + beauty niche）。
