/* Glassmorphic reading column (Andy directive 2026-06-22).
   The middle reading panel is the visual focus: a see-through dark-glass
   column that blends into the galactic .blog-page background behind it, with
   the glass thickened and darkened behind the running text for readability and
   a subtle 3D border (a lit top hairline, a deep bottom inset for thickness, a
   violet-tinted inset glow, and an outer drop shadow lifting the column off the
   galaxy). The centered max-width plus the side padding leave the galaxy peeking
   around the outside edges. WDC palette only, zero green. NO overflow clip here:
   the inline .figure blocks intentionally bleed wider than the text via negative
   margins and must stay visible over the glass. */
