 | NS theme — product detail page  (views/frontend/ns/product-detail.php)
 |
 | Everything here is scoped under .ns-pd and builds on the tokens already
 | declared by ns-theme.css. No new colours or faces are introduced.
 |
 | Why this file exists, in short: the legacy product page put the buy card in
 | `position:absolute` (so the description ran underneath it) and hid the whole
 | description behind Bootstrap tabs. This lays the page out as one grid with a
 | sticky rail, and renders the tab bodies as anchored sections instead.
