/* Account Maps — public research series (/research/account-maps/*)
   ----------------------------------------------------------------
   Responsive web edition of the account-map document design system
   (docs/design-account-map.html in the account-map-design worktree),
   converted from fixed 8.5×11 print pages to fluid long-form sections.
   Loaded per-page via {% block page_styles %} in _map_base.html, on top of
   landing-shared.css (nav, footer, .btn-*, .rp-lock-svg). Everything below
   is namespaced under .am-page / .am-doc so nothing leaks into other
   landing surfaces.

   Redaction language (mirrors the research-page contract): locked people
   render a NEUTRAL GRAY lock pill (.am-lock) — purple is reserved for the
   page's conversion CTA (.am-cta), so every locked row reads as "in the
   full map", not as page decoration. Locked data is ABSENT from the HTML,
   not blurred over. */
