selection + selection-bar in tabs.js carried six #443 cookies + two
#596 cookies — most marking the bulk-bar architectural decision
('actions live in bar, not on per-card buttons; manager not
special-cased') or the SW4RM-tab gate. All scrubbed; the canonical
docs/web-ui.md::Selection bar section already covered the bulk
actions in detail but was missing a preface for the **interaction
model** itself (how selection enters/exits, why per-card buttons
moved). Added that as the opening paragraph of the section so the
in-code refs have something to point at.
Net in this batch:
- tabs.js: -8 #NNN refs (#443 ×6, #596 ×2)
- docs/web-ui.md: +9 lines (interaction-model preface)
- functional code unchanged; build clean
refs #712
