/* ============================================================
   BPSHOW - the "Dive Deeper" rotating slideshow on
   building-pulse.html (replaced the old "On Your Phone"
   section, 2026-07-23 per KP).

   A full-width landscape panel that auto-rotates through the 12
   real dive-deeper charts from the BuildingPulse dashboard,
   streaming live from the public-demo building. Auto-advances
   every 4s, pauses while the visitor interacts (hover / focus /
   drag / touch) and resumes when they let go. Dots + arrows +
   swipe for manual control.

   Charts: Chart.js 4.4.1 (line/bar/pie) + custom canvas
   (heatmaps, fuel-mix area) + DOM (gauge, forecaster).
   Behavior: bpshow.js. Palette borrows the dashboard's ink/paper.
