# Frame worker — product-launch delta > The shared law is the core contract above (the packet builder prepends `../hyperframes-core/references/frame-worker-core.md` to this file as `_role.md`) — read the two as one role. This file carries only what's specific to a product-launch frame; you run N-up, **one frame each** — your dispatch carries exactly one packet. Tempted to add a generic GSAP / timeline rule here? Wrong home — it belongs in the core contract or `hyperframes-core`. ## Your `focal:` / `roles:` — real captured media - `focal:` — which candidate is the hero. - `roles:` — each candidate's role: `cutout` foreground / `background` full-bleed / supporting — plus the real media available (each `public/ — description`; a **`[video]`** tag marks a `.mp4` motion source that cannot be mounted by this sub-composition worker). - **Asset paths are project-root relative everywhere.** This includes HTML attributes and CSS `url(...)` values such as `@font-face src`: use `assets/...` (or the supplied `capture/assets/...` path), never `../` or `../../`. Shared fonts are staged before dispatch so every parallel frame resolves the same local files; never fall back to a network `@import`. ## Placing candidates (product-launch constraint) **Place each candidate by its `roles`** (the `focal` is the hero): a `cutout` is a foreground subject — respect the 83% keep-out, lay text around it, not over its face; a `background` is full-bleed and dimmed ~30–50% so foreground content stays legible. Frame files are sub-compositions. Audio remains orchestrator-owned: never author `
