/* Video workbench refine (2026-09-27, owner-reviewed).
   Loaded after the page's own styles; CSS only — no markup/JS dependency.
   - nav: full-width bar with a hairline, like the public site; flat key chip
   - decorative containers removed (audio row card, floating submit card)
   - option chips (resolution / duration / aspect) keep their bordered
     selected state — that is functional, not decoration
   - "+ 添加参考" is a visible secondary button
   - model <select>: solid closed state, single border, native popup
   - key input focus: one border colour change, no extra glow ring */
