DO
Keep the Jira mark's blue gradient intact and upward-facing
Use ADS status colors consistently — To Do neutral, In Progress blue, Done green
Pair issue-type and priority with an icon, never color alone
Set issue keys and metadata in the mono stack
Keep the board neutral so colored cards and lozenges lead
DON'T
Don't flatten or recolor the Jira gradient mark
Don't invent dark surfaces; anchor on the real ADS neutral scale
Don't reuse a status color for an unrelated meaning
Don't set issue keys in a proportional font
Don't put more than one primary button in an action group
