Fix the far-field threshold. The current assertion checks no particles.
setup() uses a 1200×800 field, so radius = ringRadius(1200, 800) = 240. The motion center is at (600, 400). The farthest grid particle is about 721 px from the center. The condition d > radius * 4 requires d > 960, so no particle meets it. farMaxLevel therefore stays 0, and expect(farMaxLevel).toBeLessThanOrEqual(1) on Line 108 passes for any computeFrame output. The test does not check the claim in its comment that far particles are drawn only as faint dots.
You can use radius * 2.5 (600 px). The corner regions of this field are past that distance. At that distance, the envelope is about 0 and haloFalloff * HALO_FLOOR is about 0.04, so the ambient term dominates and the expected level is 0. You can also assert that at least one particle matched, so the check cannot become vacuous again.

Remove the encryption claim from login.secure.
HttpOnly prevents JavaScript from reading a cookie; it does not encrypt the cookie or the session. The Chinese login page currently tells users that it does. Replace “加密保护” with wording that describes the protection actually provided. (developer.mozilla.org)

Do not present fixed demo figures as current production statistics.
STATS contains fixed values, including a count labeled “Alarms today.” The statistics card also renders when DEMO_MODE is false. A real deployment therefore shows invented device and alarm figures as current figures. Restrict the card to the demo, or load real statistics before showing it in real mode.

Keep the narrative in flow below the xl breakpoint.
At 1024px, the narrative can extend from x=40 to x=616. The sign-in card can start at x=440, so their horizontal ranges overlap. Their vertical positions can also overlap at common desktop heights, allowing the card to cover part of the narrative. This is a localized visual defect, not a major workflow failure.

Do not link a real deployment’s build hash to the template repository.
REPO_URL points to the template repository, but this footer link also appears outside demo mode. If a deployment builds from a fork, its commit hash need not exist at this URL. Use a configurable repository URL or leave the hash unlinked outside demo mode.
