   9255 W Alameda — Mercury Bold component library v1
   Imports `design-system.css` first.

   Every component below is composed from tokens. No new colors, no new
   spacing values. Add new components here rather than inventing in
   page-specific CSS.

   Components included:
     · .ms-shell     — page shell + chrome
     · .ms-page-head — page header (title + lede + actions)
     · .ms-card      — section card
     · .ms-tile-row  — KPI tile row
     · .ms-tile      — single KPI tile (with .revenue / .expense / .cash / .neutral tints)
     · .ms-btn       — buttons (primary / secondary / ghost / danger / success)
     · .ms-input     — text/select/date/textarea inputs
     · .ms-table     — data table
     · .ms-pill      — status pill (good/warn/bad/info/neutral)
     · .ms-empty     — empty state
     · .ms-loading   — loading state
     · .ms-error     — error state
     · .ms-toast     — toast notification
