The drawer's :host had transform: translateX(...) which makes it the
containing block for any fixed-position descendants. The .scrim at
'position: fixed; inset: 0' therefore covered only the drawer's own
420 px panel area, not the viewport. Visible symptoms:
- Page behind the drawer didn't dim
- Click outside the drawer didn't dismiss it (no scrim to receive)
- Felt like the drawer wasn't really 'modal'
Fix: keep :host as a fixed full-viewport overlay (no transform),
move the drawer body into an inner .panel div, transform only that.
Now the scrim covers the viewport correctly and outside-clicks dismiss.
Same trap exists nowhere else; nv-modal already follows this pattern.
