   .s-agents-md — Act 4 opener.
   "Encode project-specific knowledge."

   Step 0 — Knowledge:
     A real AGENTS.md excerpt (fabric8 K8s client) with three
     annotated gems: canonical command, operational gotcha, CI
     reproduction. The audience reads the artifact, not bullets.

   Step 1 — Rituals (tell-then-show on the canonical command):
     The AGENTS.md panel collapses to its top section and the
     callouts dim. A Makefile / build.gradle.kts side-by-side
     reveals below — the same `quick-build` ritual in two
     dialects — followed by an agent-invocation caption.

   Theme: light slide. Code artifacts (AGENTS.md panel, Makefile,
   Gradle) stay dark terminals so they read as files, not text
   blocks. Same idiom as s-code.light.
