   v2 · corporate restraint: the standard film hero, the three research questions as a calm statement beside the
   two paragraphs, a slim affiliation row between hairlines (not a card), then two publication sections that share
   one frosted card design: header (eyebrow + Heebo 900 heading over a thin rule), 2 columns, 1 on phones.
   In a card the hook question is the one blue line (the lay reader's way in); chips differ by tint and wording.
   One hue (navy / blue), flat fills, no orbs, rings or glows. Nothing moves but the reveals. */
