   TickmarkTools — Universal Tool Page Template v2.0
   One shared stylesheet, inherited by every tool page (500+ scalable).
   Depends on CSS custom properties already defined in assets/style.css
   (--bg, --surface, --ink, --ink-soft, --primary, --primary-dark, --border,
   --card-bg, --radius). This file only ADDS to that system — it never
   redefines brand tokens.
