/* R&D hero masthead: the LEFT text block flows EXACTLY as the original single-
   column mast (top-aligned, full-width text, .deck capped at 66ch). The Bio-
   Labtory diagram lives ONLY in the previously-empty RIGHT area as an absolutely
   positioned figure, so it never reflows or narrows the text. It sits directly
   over the .mglow green glow with NO white card; the transparent PNG floats on
   the cream surface and a soft drop-shadow gives it depth. .mast is already
   position:relative, so the figure anchors to it. Scoped to .rnd-mast so other
   .mast pages are unaffected. .mglow/.mframe stay absolute (z-index:0) below. */
