// 2026.3.12 ballooned to ~213.6 MiB unpacked and correlated with low-memory
// startup/doctor OOM reports. 2026.4.12 intentionally stages Matrix runtime
// dependencies, including crypto wasm, so packaged installs do not miss Docker
// and gateway runtime dependencies. Keep the budget below the 2026.3.12 bloat
// level while allowing that mirrored runtime surface.
