/* Phase 3.5 fix - oem-manufacturing.html only. Its bundle pairs site-base.css (the legacy dark
   header) with this refined shell, so two legacy rules survive:
     .nav-links a:not(.btn) { color: var(--meta) }        -> #AAB2BB nav text on a white bar
     .language-select { font-family: var(--font-mono) }    -> monospace language selector
   The .nav-links rule wins on specificity (0,2,1 vs the 0,1,1 refined rule) and the refined
   .topnav{background:#fff} never reset colour, so that header rendered #AAB2BB (1.9:1) text
   where every other page renders var(--ink). Scoped to .oem-page: no other page is touched,
   and [aria-current] links keep the refined blue. --font-body keeps the CJK override, with
   inherit as the fallback on pages that do not define it.
