+- **No plan = stop.** If your `### Groups` is `TBD`/empty (Step 3 was skipped), report back and write nothing — never invent groups, templates, or copy.
 - **The plan** is set in your `## Frame` block: the groups, templates / primitives, copy, brand,
   and anchors. Build it as written. If a plan is genuinely wrong (wrong template or copy), stop
   and report — the orchestrator re-plans at Step 3.

 If a command fails, surface stderr and stop. Do not pile on recovery commands. If a gate names a frame, fix `compositions/frames/NN-*.html` with the cheapest safe fix: edit the frame HTML for a local issue; re-dispatch the frame worker only when the whole shot must be rebuilt.
 
+**Known false-positive — do not chase it.** `inspect` may report a handful of `text_box_overflow` errors of ~1–4px on the **caption** highlight words (selector `#caption-word-*` / `.caption-line`). The caption pill uses a deliberately snug `line-height` (set once in `scripts/captions.mjs`) and has **no `overflow:hidden`**, so a heavy display glyph's ink spills a few px into the pill's own padding — nothing is actually clipped. Treat these as expected and proceed. Do **not** inflate the caption `line-height` (it balloons the pill, which is worse) and do **not** re-dispatch a frame for them. Only act on a `text_box_overflow` when it names a **frame** element (`#el-NN-*`), not a caption word.

 After checks pass, pause for user review. The video is assembled, viewable, and editable in Studio. Manage preview only once across Step 3 and Step 6: open it if the user asked earlier, offer it if they declined earlier, and do not ask again if they are already reviewing in Studio.

 1. **Read** — `hyperframes-core`'s composition contract (the structural law), then `frame.md` (the look) and your `## Frame N` block (content + effects / blueprint / assets). **Then open the recipe body of every id the block cites** — `ANIM_DIR/rules/<id>.md` per effect and `ANIM_DIR/blueprints/<id>.md` for the blueprint (plus its linked `examples/<id>.html` when the recipe is unclear): you reproduce these, 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 `lint` / `validate` / `inspect` can miss the resulting blank sub-composition.
 2. **Design** — translate `scene` + the (sometimes shot-by-shot) narrative + the recipes you just read into a visual plan using `frame.md`'s components and type ramp. Honor the note's phases shot-by-shot per the whole-shot rule above, and find a visual idea that reinforces the beat, not a literal restyle of the words. Place the named assets.

-The orchestrator runs `lint` / `validate` / `inspect`; catch these yourself first (codes are `hyperframes lint`'s; the rules behind them are in `hyperframes-core`):
+You **can't** meaningfully run `hyperframes lint` / `validate` / `inspect` here: they operate on the **assembled project** (the `index.html` graph / bundle), and your frame isn't wired in yet — so they report on _other_ files, not yours (a false green). The **orchestrator** runs them at **Step 6, after assembly** (the correct unit), and **re-dispatches you with the finding** if your frame fails (see **Retry** above). So get it right on write: re-read your file against this checklist before finishing — the codes in parens are `hyperframes lint`'s and what the orchestrator may cite back (the rules behind them live in `hyperframes-core`):
 
 - `missing_template_wrapper` / `missing_composition_id` — root is `<template>`-wrapped and carries `data-composition-id="<frame_id>"`.
 - **Template transport** — every `<style>` and `<script>` block, including the GSAP load, lives inside `<template>`.
+- `subcomposition_root_styled_by_class` — **style the frame root via `#root`, never a class on the `data-composition-id` element**: at render a class on the root gets scoped to a descendant selector that can't match it, so the **whole scene renders unstyled** (Studio preview still looks right — trust this rule, not the preview). Descendants use plain selectors.
 - `clip_missing_data_attrs` — every `class="clip"` element has `data-start` / `data-duration` / `data-track-index`.
 - `timeline_not_paused` / `timeline_not_registered` — one paused timeline, registered at `window.__timelines["<frame_id>"]`.
 - `css_transition_used` + repeat / yoyo / non-deterministic logic — none present (the renderer seeks frame-by-frame).
