/* ============================================================
   Atlas Marketing — shared patterns extracted from inline
   <style> blocks across templates/index.html, brand.html,
   careers.html, download.html, legal/index.html, account/auth.html
   (the unified login/signup page), link_in_bio.html.

   All classes prefixed `.fm-*` (Atlas Marketing) so they
   never collide with the foundation's `f-*` (components) or
   `u-*` (utilities) prefixes. All values reference --f-*
   tokens — light by default, dark via [data-theme="dark"].

   Templates adopt these incrementally — adding `class="fm-X"`
   to existing markup is non-destructive because the legacy
   inline `<style>` rules still apply alongside.

   Migration recipe per-template:
     1. Add fm-* classes to existing elements
     2. Verify visually
     3. Remove the now-redundant inline <style> rule
