When hovering a constellation node, skill pill, or timeline item,
non-related UI elements across all components dim to 0.25 opacity,
creating a focused visual relationship view. The constellation axis
and year labels also dim via CSS class. Respects reduced-motion.
Single source of truth for expand/collapse card interaction pattern:
container styling, keyboard handling, chevron rotation, AnimatePresence
animation, and expanded content wrapper. Each consumer retains unique
header and body content via render props.
Create src/lib/theme-colors.ts with DOT_COLORS, KPI_COLORS,
PROJECT_STATUS_COLORS, and DEFAULT_ORG_COLOR constants. Add
motionSafeTransition() utility to src/lib/utils.ts.
Removes 6 duplicate color map definitions across Card, DetailPanel,
PatientSummaryTile, KPIDetail, ProjectsTile, and ProjectDetail.
Replaces 9 hardcoded '#0D6E6E' fallbacks and 7 inline motion ternaries.
Fixes project status color inconsistency between ProjectsTile and
ProjectDetail (Ongoing was teal in tile, amber in detail).
