waterfall-bridge
Waterfall variant with start/end total bars + delta bars between.
Two anchor bars (start, end) flanking a series of deltas. Common in IR decks for FY variance walks where reader needs to see beginning, ending, and deltas in between.
When to use
Variance walks where the start and end totals are themselves news (need anchoring).
When NOT to use
No explicit start/end values matter (use plain waterfall).
