/* web/pages/agents/agents.css — [AGX1 agents-page-v1] · [AGX3 screenshot-v1]
   Agents page, three columns: Teams (240) · list · detail.
   [AGX3] restyled to Sarthak's reference screenshot (2026-10-12):
     - three surface layers (kit 2.1): team column --list, list and detail
       on --bg, every card/box on --surface
     - line icons (.agx-ico) instead of emoji, 1.7 stroke like the rail
     - detail = title + actions, pills, description, readiness alert, then a
       2x2 grid: Ask it things like · You get back · Safety rules · Sources
     - pills by meaning: lime = done/connected, amber = needs action,
       neutral outline = facts (Built-in), accent tint = team/template
   Scoped under .agx so nothing leaks into the rest of the shell. Tokens
   only; the shimmer reuses brandkit's global bk-shimmer keyframes. */
