   - `roles:` — each candidate's role: `cutout` foreground / `background` full-bleed / supporting — plus the real media available (each `public/<basename> — description`; a **`[video]`** tag marks a `.mp4` motion source that cannot be mounted by this sub-composition worker).
   - `sfx:` — the orchestrator's; you mount no audio.
 - `frame.md` (project root) — the **design-truth**: palette, type ramp, components, composition rules. The LOOK. Pull every visual token from here.
+- **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 `../../`. Stage shared fonts before dispatch so every parallel frame resolves the same local files; never fall back to a network `@import`.
 - `RULES_DIR` — absolute path to this skill's local `../hyperframes-animation/rules/`. The **named motion verbs in the Scene lines** (and the moves the blueprint cites) resolve to rule recipes here: `RULES_DIR/<id>.md` is the mechanics for a motion. (A few rules link an optional runnable demo in the shared `../hyperframes-animation/examples/<id>.html` — open it only when a recipe is unclear.)
 - `../references/cut-catalog.md` — the **cut catalog** (zoom-through / inverse / cut-the-curve / waterfall). When a Scene seam is a within-scene swap, a scene-to-scene cut, or a text-to-text line change, build it INSIDE your composition per this catalog (Z-scale + blur + opacity, or per-word x-staggers). You never author the between-frame transition — story's `transition_in` + the injector own that.
 - Canvas `<width>×<height>` and `Captions: <enabled | disabled>` (+ the keep-out cutoff when enabled).

 1. **Read** — `hyperframes-core`'s composition contract (the structural law), then `frame.md` (the look) and your `## Frame N` block (the shot sequence + `blueprint:` / `focal:` / `roles:` / assets). **Then read the blueprint template** `../hyperframes-animation/blueprints/<id>.md` (skip if `compose`) for the shot's shape and signature move, and **open the rule recipe `RULES_DIR/<id>.md` for every named motion** in the Scene lines (plus the shared `../hyperframes-animation/examples/<id>.html` when the recipe is unclear): you reproduce these mechanics, not improvise them. Internalize the self-check codes below before you write — most lethal is **template transport**: every `<style>` + `<script>` (including the gsap load) must live INSIDE `<template>`, because the runtime only clones template contents and the assembled-project `lint` / `check` gate can miss an unwired blank sub-composition.
 2. **Design** — turn the time-coded shot sequence into a timeline using `frame.md`'s components and type ramp: each Scene window becomes a phase revealed on its `voiceover` cue, each named motion built from the recipe you just read, the blueprint's signature move kept recognizable. Place the named assets, and find a visual idea that reinforces the beat, not a literal restyle of the words.
 3. **Author** — write the full sub-composition to `compositions/frames/<frame_id>.html` (rewrite to iterate; last write wins). `<template>`-wrapped root carrying `data-composition-id="<frame_id>"` and styled via `#root` (not a class on that element — see the self-check below), exactly one `gsap.timeline({ paused: true })` registered at `window.__timelines["<frame_id>"]`, built synchronously — per the core contract.
+   Prefix authored ids and globally reusable class names with `<frame_id>-` so sibling frames assembled from parallel workers cannot collide. Contract selectors such as `#root` and `.clip` are the only exceptions.
 4. **Self-check, then finish** — re-read your file against the checklist below and fix in place. Writing the file is your terminal action; you do **not** run the CLI.
