   techtuate "Flow" page layer for tool pages and articles.
   Load AFTER /assets/flow.css on every tool page, /vs/ page and article.
   It provides:
   - the page frame: .tt-main, .tt-backlink, .page-head, .tool-ui (the glass
     panel the tool lives in), .tt-section (about / FAQ blocks), .cross-compare
   - shared components: .btn (.alt = yellow primary, .ghost), .callout, .cta,
     .section-head, .pill, .compare tables, .prose articles, form controls,
     #copy-flash toast
   - token names the tools' own CSS uses (--ink, --bg, --field, --line,
     --yellow-*, --font-*, --r-*), set to dark Flow values.
   The home page and /card-reader/ are built on flow.css alone.
   See docs/design-system.md.
