# Resource comparison for the site (source data)

All on the same MacBook Pro M3 Pro (built-in display 2560×1600, on power, quiet Mac), each app's own scene running,
"extra over a static desktop". CPU = app + WindowServer (% of one core); GPU = system GPU % added; Energy = whole-chip power added.

| App (scene measured) | Energy | CPU | GPU | RAM | Date / source |
|---|---|---|---|---|---|
| **Locker Plus — Wisteria Nap (lightest)** | **100 mW** | **6.9 %** | **2.2 %** | 149 MB | 2026-10-01, docs/THEME_RESOURCES.md (WebP build) |
| Locker Plus — Lilies Field | 190 mW | 8.1 % | 3.7 % | 159 MB | same |
| Locker Plus — median of 24 scenes | ~221 mW | ~12 % | ~4.7 % | ~160 MB | same |

Owner's instruction (2026-10-02): put our resource use vs the competition on the site as a USP, "the best numbers", table format.
Claude's choice for the site table: Locker Plus row = Wisteria Nap (lightest); columns Energy, CPU, GPU (RAM omitted: not a
differentiator). Headline ratio vs the heaviest competitor: 3,256 / 100 ≈ 32× less energy; vs Backdrop ≈ 7×.
