   BFS Retention Command Center — design tokens
   Measured from Klaviyo app screenshots (help.klaviyo.com, Nov 2026):
     primary button #1d1e20 · body text #1c1c1c · column headers #4c4c4c
     canvas #f3f4f5 · dividers #ebedef · row rule #efefef · input border #949494
     status pill #ecedef · link blue ~#4374a5 · selected menu row: pale blue + 3px blue bar
   Inferred (not visible in any screenshot we could obtain): the sidebar's exact width and
   active-row fill, and the typeface name. Screens render in the platform UI face, so we use
   the system stack. See DESIGN.md.
