/* TaskTrack Pro — design tokens.
   Palette seeded from the sketch's visual.palette (#2f6df6 brand on #0b1020).
   OUR REASONING: the three category hues are the app's only decorative colour.
   The research design floor says "prioritize clarity over visual flair" and
   "use familiar, developer-native categories", so colour carries category
   identity and nothing else — never mood, never emphasis. */
