For Support

The short version

Customers won't notice this PR, so it shouldn't generate tickets. Nothing about the clinic-web app's behavior, appearance, or performance changes for them — this only affects how the engineering team's internal per-branch preview builds are produced.

What to know anyway

• If you ever hear engineering mention a "sandbox build" or a branch preview link

behaving oddly (slow, failing, or the preview link 404ing), that's the environment this PR touches — it's an internal engineering tool, not something a clinic user would ever interact with directly.

• If a customer-facing report ever does mention something that looks build-related

(blank page, missing assets, stale-looking UI after a release), this PR is not a likely cause: it's inert on real production builds by design — the optimizations only apply when the internal SANDBOX_BUILD variable is set to 'true', which production release builds never do.

Escalation guidance

There's no new "known issue" or workaround to add to support scripts for this PR. If something does look build-related in production, escalate as you normally would; don't reference this PR as a probable cause since it can't run outside the sandbox pipeline.
