   NOVA · MEET NOVA — INTERACTIVE STORY
   Namespace: nvst- (nova-story) — every class starts with `nvst-`
   so class names never collide with external / WordPress theme CSS.

   ISOLATION LAYER: element-level theme styles (e.g. theme.css doing
   `button { border-radius: 0 }` or `p { margin: 1em 0 }`) can still
   slip past the class prefix — the resets below neutralize those
   inside our tree without touching anything outside it.

   Every reset uses :where(element) to zero out the element portion
   of specificity, so the resets sit at (0,1,0) — the same level as
   our .nvst-* class rules. Source order then lets our own class
   rules (defined below) win, while external theme rules still get
   filtered out by name.
