fix(css): featured verdicts vertical-rhythm — tighten badge→title, widen inter-card gap (v2.1.5)

Issue 1: badge→title gap tightened from 16px to 8px.
  Verdict badge is a label for the peptide name; card's uniform gap: --spacing-md
  made them look like separate paragraphs. Fix: margin-top offset on __title.

Issue 2: inter-card gap increased from --spacing-xl (32px) to --spacing-2xl (48px).
  Cards were visually merging into a single block. Card-to-card gap must clearly
  exceed within-card gaps to maintain the three-card hierarchy.

No functional or template changes — CSS-only.

+
+### Changed
+- `.hero-featured-verdicts__grid`: grid `gap` increased from `--spacing-xl` (32px) to
+  `--spacing-2xl` (48px). Cards were too close together, making the three verdict cards
+  read as a single visual block rather than three distinct entries.
+- `.hero-verdict-card__title`: `margin-top: calc(var(--spacing-sm) - var(--spacing-md))`
+  added (−8px offset). The verdict badge and title are a label/heading pair; the uniform
+  card `gap: --spacing-md` (16px) created too much separation between them. Effective
+  badge→title gap is now 8px; title→summary gap remains 16px.
