   GRID + LAYOUT SHIM  (replaces bootstrap.min.css, ~140KB)
   Implements exactly the Bootstrap-4 class contract the markup
   already uses — container / row / col-* / navbar / a small set
   of flex, spacing and text utilities — so no template markup
   had to change. Breakpoints match Bootstrap 4 (sm576/md768/lg992).
