Git archaeology: the grid was never a deliberate removal. It lived as a fixed
`body::before` in index.html's inline <style> block and was dropped when bed8675
("D3 Part 2: index + kapcsolat on design system v2") migrated the page onto
site.css. dd54e4c, which created site.css, has no body::before — it was a
porting omission, and nothing took its place. No asset was lost; it was pure CSS.
Restored at its original geometry and subtlety (50px cells, 1px lines, 3%), not
redesigned. Only change: the accent is the v2 --blue #0083D8 instead of the
retired legacy #0088cc, which site_gates.py bans. Scoped to body.page-index
because index is the only page that ever had it.
site.css cache-bust bumped to v=2 across all seven pages (nginx caches 7d).
