/* AIStackCost — a deliberate mix of two sibling identities within the
   Modernist/Ascua family, not a new one from scratch:
   - MoveBudget contributes the accent color (amber) and Archivo Expanded
     for big numbers/headings — fits a cost calculator's "money" moments.
   - MealPlanSheet contributes the secondary "good value" tone (sage) used
     to flag the cheapest model, and its soft 6px radius, which keeps a
     dense comparison table from reading as a bare spreadsheet.
   Layout mirrors budgetreset/style.css (inputs + sticky summary grid,
   numbered cards, FAQ) so the two assets read as one family. */
