When five button variants belong in one swipe
UX critiques love sequential PNG decks contrasting baseline vs explorations—lossless chaining avoids JPEG mosquito noise betraying hairlines. Naming discipline encodes intent so PMs read deliberate iteration—not chaos. Transparent PNG stacks demand consistent mattes or reviewers mis-attribute regressions to phantom tint shifts. Ai2Done merges with drag-sort UX plus explicit progress; juxtapose highest-contrast neighbors first to validate seams. Printing? Ensure non-transparent ink coverage exists or toner sinks into invisible gaps nobody budgets.
Merge PNGs in three steps
- Encode filenames with iteration metadata.
- Upload, reorder, merge, preview transitions.
- Attach changelog PDF cover emails before critiques.
