/* web/workflows_page.css — [WFX1 workflows-page-v1] · [WFX5 house-layout-v1]
   Workflows on the house layout shared with Agents and Projects (Oct 12
   2026): vertical column (--list) | list with fold groups (--bg) | detail
   (--bg), cards and boxes on --surface; line icons (.wfx-ico); pills by
   meaning - lime done/connected, amber needs you, red failed, accent
   running/vertical/template. Scoped under .wfx; TOKENS ONLY (acceptance
   4.5); every selector defined once; no page-local keyframes (the shimmer
   is brandkit's bk-shimmer). The old .wfp-* markup stays dormant. */
