/* Open Questions — below-the-fold analytical layer on per-episode MCG
   pages. Surfaces BRAID risk_flags in the founder's own voice.

   Aligned with the project's "AVICI card" recipe (docs/design-tokens.md
   §4): gradient surface, subtle gold top accent, terracotta typography.
   Editorial voice: press kit with footnotes (Claude-skills/mcg-daily/
   SKILL.md → Editorial Voice).

   The section is restrained relative to the AVICI panels above — no
   hover lifts, no glow expansion — because it's a footer, not a
   feature. The gold accents are present but quieter. */
