v0.8.43

# HyperFrames v0.8.43

Released on 2026-09-16.

Portrait compositions no longer render clipped when the project was scaffolded at a different size, and `hyperframes lint` now warns before you render when the scaffold's `html, body` size drifts from the root. Render telemetry gains per-tag and failure-type detail, and docs search shows catalog source file names correctly.

## Fixes

- **Core:** Size `html` and `body` to the composition root at runtime. A portrait composition (for example 1080x1920) in a project scaffolded landscape used to render only its top 1080px, with the page background below. It now renders the full frame. Fixes [#4001](https://github.com/heygen-com/hyperframes/issues/4001) ([eb0957a49](https://github.com/heygen-com/hyperframes/commit/eb0957a497208e72fda82952410d14dcb03cce77), [#4005](https://github.com/heygen-com/hyperframes/pull/4005)).
- **Lint:** New `root_dimensions_mismatch` warning. It fires when the root's `data-width`/`data-height` disagree with the `html, body` CSS size or the viewport meta, so the drift shows up in `lint` and `check` before a render. Sub-compositions saved as full HTML documents can trigger this warning even though the parent composition sizes them; it does not affect renders, and a fix follows in the next patch ([eb0957a49](https://github.com/heygen-com/hyperframes/commit/eb0957a497208e72fda82952410d14dcb03cce77), [#4005](https://github.com/heygen-com/hyperframes/pull/4005)).
- **Docs:** Catalog page "Source" section titles are now plain strings, so docs search shows the file name instead of `[object Object]` ([7b5fdb1ad](https://github.com/heygen-com/hyperframes/commit/7b5fdb1ad28347272d235edea7aa6a9c762d5e1c), [#4006](https://github.com/heygen-com/hyperframes/pull/4006)).

## Features

- **Telemetry:** `render_complete` events now include `composition_element_tags` (a count per element tag), `aroll_video_count`, and `heygen_video_count`. `render_error` events add `error_name` and `failed_stage_code`, so failures can be grouped by error type and pipeline stage ([3704863d9](https://github.com/heygen-com/hyperframes/commit/3704863d966aa2bbee305e69b4f8dbfa0b93090b), [#4004](https://github.com/heygen-com/hyperframes/pull/4004)).
