Overview

When a user toggles light/dark in hero_os, every child surface (iframe islands, native islands, admin UIs) should follow. Today the propagation is partial — some surfaces stay dark / stay light regardless of the OS toggle.

Why

Meeting 2026-05-06: "hero_theme / hero os / if there follow light".

Existing pattern documented in skill hero_ui_theme and web_embed. This issue tracks wiring it everywhere it should be.

Acceptance

  • Every iframe island receives the theme via the documented postMessage bridge
  • Every native (Dioxus) island reads the OS theme signal and applies data-bs-theme
  • Visual test (Hero Browser MCP) toggling light/dark in hero_os and asserting every island follows
  • List of non-compliant surfaces audited and ticked off
