/* Mobile-friendly tables: horizontal scroll instead of layout blowout.
   display:block on <table> works for scrolling but strips its implicit
   ARIA table/row/cell roles, so header/cell association becomes invisible
   to screen readers even though the sanitizer allows scope/headers through
   (config/initializers/action_text.rb). public.js wraps each table in
   .field-table-scroll on boot; wrapped tables get their real display back
   below. This rule stays the fallback for no-JS and the brief pre-boot
