slice 4: accent palette refinement — blue → teal

Replace the four accent-family hex codes site-wide with the teal palette
(keeps the dark theme; only swaps the accent family, not the dark base):

  #3b82f6 (accent primary CTA)   → #5B7C8D  (teal)        [839×]
  #2563eb (accent-dark / hover)  → #4A6473  (darker teal) [44×]
  #60a5fa (info link, lighter)   → #8FB0C3  (mid teal)    [68×]
  #1e3a5f (accent-muted bg)      → #2F4F5F  (navy)        [44×]

tailwind.config.js tokens updated to match (accent/accent-dark/accent-muted).
Sweep also covers tailwind.css. 108 files touched. The dark base (#0d0d0d,
#111, #161616, #1a1a1a etc.) is intentionally untouched.
