/* ═════════════════════════════════════════════════════════════════════════
   Signal over Noise — hírlevél-oldalak (issue + archívum)

   AIBP ACADEMY BRAND. Ugyanaz a vizuális nyelv, mint a leckéken és a
   dashboardon: cream paper-dotted, Inter / DM Mono / Caveat, LILA accent
   (#783FF3). NINCS Playfair, NINCS narancs, NINCS kitalált wordmark — a
   logót a platform-shell adja (AIBP Academy lockup), itt csak a tartalom van.

   A "Signal over Noise" a heti rovat neve, az Academy saját fejléc-mintájában
   (DM Mono kicker + Inter cím), pont mint egy lecke-hero.
