Five missing line-height values caused pixel shifts when Tailwind
utilities (text-sm, text-lg, text-xs) were replaced with semantic
classes that only set font-size. Also remove phantom padding-bottom
on .admin-header (the old pb-4 utility was never defined).
Fixes: .admin-header, .admin-header-subtitle, .admin-error,
.admin-brand, .admin-text-secondary

9-phase plan to replace Tailwind v4 and DaisyUI with hand-written
CSS using @layer, native nesting, container queries, oklch, and
@property. Visual regression testing at each phase. ~22h across
14 sessions.
