homepage: shrink Staff Editorial header to match The Latest

Earlier this evening I bumped the Staff Editorial header to a
font-serif 2xl/3xl bold — too loud, fought with The Latest section
header below it on the same page.

Reverted to the same shape The Latest uses:
  <span class="section-label">Staff Editorial</span>
  <div class="flex-1 h-px bg-[#2a2a2a]" />
  <Link>All featured →</Link>

That's the global .section-label utility (font-body 13px,
font-weight:700, letter-spacing:0.08em, uppercase, color
accent-blue, with a 3px accent border on the left). Now the two
section headers on the homepage are visually consistent.
