/* layercell design system — forms, data, and state
   Load AFTER layercell.css. Hosted pages and internal tools both use this.

   Everything here obeys the same rules as the rest of the system:
     · Signal marks state, focus and links. Never a fill, never a heading.
     · Depth is layer offset + opacity. No shadow, no scrim.
     · Adjacent surfaces share one hairline.
     · 44px hit floor on anything a merchant touches.
