Introduce shared Remotion utility barrel export

Objective

Create a centralized export layer for all Remotion shared utilities.

---

Why this matters

Remotion utilities are currently imported inconsistently, increasing coupling and duplication risk.

---

Parallelization metadata

Track

remotion

Depends on

• Centralize timing constants #45
• Extract shared captions utility #44

Safe to run in parallel with

• pipeline validation

Merge risk

• low

---

Files in scope

Primary:

• remotion/lib/index.ts

---

Required implementation

1. Create barrel file

Export:

• captions
• constants
• hookTiming
• transcript validation utilities

2. Standardize imports

All consumers should use:

remotion/lib

---

Constraints

• no behavioral changes

---

Acceptance criteria

Functional

• imports unified

Integration checks

• no deep imports remain

---

Verification commands

Search deep imports:

grep -r "remotion/lib/" remotion/components/

Expected result:

• only barrel imports remain

---

Explicitly out of scope

• restructuring utilities

---
