Please write for people who don’t have full context; link to related issues and documentation!

• Divergent color ramps:

  • Improve CSS for displaying disabled min/max input fields

  • Improve label of “Use actual range” button -- include the data min/max in the label! Thanks, Yao-Ting!

  • Minor refactors for readability (extract named boolean, leave props packed in object called props)

  • Only render min/max controls for graduated & singleband symbology modes

  • Fixup critical value display to use selected min/max, remove hardcode

  • WIP: Fixup saving/loading min/max/reverse from the shared model. Previously, these values were only “saved” in the downstream classified color stops, and when re-opening the UI they’d reset to default. Now, they save into the shared document, but they don’t successfully load from the shared document (yet!). Pushed a WIP commit.
