   Donut + 12-lead grid that sit below the 2a heart inside

/* ---------- Side-by-side layout: heart | donut | grid ----------
   #mapper-mount has exactly two direct children — the 2a heart (.hvo)
   and the 2b panels host (.ctp-host, whose .ctp-row holds donut+grid).
   Lay them out as one row so all three panels sit side by side (as the
   Prompt-2 mapper did); the heart is shrunk to make room. */
