/* Decimal Hours to Minutes Converter — content styles.
   Prefix: --dh-  /  .dh-

   Reference point: two small, symmetric converter panels (decimal→h:m and
   h:m→decimal) sit side by side conceptually — each with its own live
   result line right under its own inputs, so both directions are visible
   without switching modes. A quick-reference table of common fractions
   follows as a scannable lookup, not something you have to calculate.

   THIS FILE STYLES THE CONTENT AREA ONLY. Chrome is owned by chrome.css. */
