/* ============================================================================
   The source stamp. Every AT6031 page that carries a figure, a grant amount or
   a standard wears one of these, and it says when the figure was last read off
   the primary record and where from.

   A page with numbers and no stamp is a page nobody can date. Use:

     <aside class="src-stamp">
       <b>Figures read 1 September 2026</b>
