NFR: Footprint

Constrain binary size and runtime memory usage.

Requirement

• Universal macOS binary size ≤ 20 MB (excluding model files).
• Peak RSS ≤ 400 MB including model during standard transcription workload.

Rationale

A lightweight application reduces download size, disk usage and keeps memory pressure low on older devices.

Acceptance Criteria

• du -h on release DMG shows ≤ 20 MB binary.
• Runtime memory measured via Activity Monitor stays ≤ 400 MB during 30 s monkey test.

Test-Driven Design

Add failing size and memory regression tests into CI before implementation tweaks.
