 * Reading order (right column, top → bottom):

 *   ② 3 keywords (UPPERCASE)    → .postcard-keywords
 *   ③ Takeaway / core proverb   → .postcard-core      (italic serif, opens the card)

 *   ⑤ Final takeaway (gold bar) → .postcard-takeaway  (closing CTA sentence)
 *
 * Also applied to the reading-result page in parallel:
 *   .reading-core        ≈ ③ (Cormorant italic, serves same role)
 *   .takeaway-title      ≈ ⑤ (gold left bar, closing sentence)
 * Keep these two sets in visual parity whenever the spec moves.
