Adds public/images/docs/ — 24 real-app screenshots covering every
module, every node, the bundles concept page, the conflicts surface,
the starter wildcard form, and the intro graph. Every DocImage caption
across overview / concepts / nodes / modules pages rewritten to name
the actual modules visible (Starter subject, Starter pairing, etc.),
the actual values shown in JSON snapshots / preview panes (tiger,
dramatic, golden hour, 1344x768, 7.5), the specific badges
(MISSING VAR, MODIFIED, OVERRIDE, DUPLICATE, CONFLICT) and the wiring
topology so a reader can map every described element to a pixel.
New doc primitives:
- DocFlow.vue — left-to-right chain illustration with stage icons
- DocRef.vue — typed cross-link chip (node / module / concept)
Registry: registers the new wp-seed-list node page.
Removes the now-redundant docs/docs-image-shopping-list.md tracking
file; everything it tracked landed in this commit.
