/*
  Host isolation + layout for n4859 header.
  Shared by:
    - hf-static-front static pages (inline/static mode)
    - Vue apps (dynamic mode) via /static-resource/seo-chrome/n4859-header-host-guard.css

  Known host conflicts:
  - zui `a{color:#666}` beats CDN for dropNav `label>a` (not `li>a`)
  - zui `label{font-weight:bold;margin-bottom:5px}` makes 运营/更多 look wrong
  - Element UI / global label rules can hit the same dropNav labels

  Layout:
  - CDN `.nav` is position:fixed and does not reserve document flow.
  - Old header.css used in-flow `.header{height:46px}`.
  - Keep #hf_header 46px tall so page content is not covered.

  Load AFTER the n4859 header CDN CSS.
