/* Design system for dense financial data.
   Two rules drive every choice here:
   - Accuracy over polish. If a treatment makes a screen prettier but a number less
     traceable, the traceability wins.
   - The product lives in empty, partial and error states, so those are designed
     first-class rather than as an afterthought. */
