+This fork builds **Glucose Guard** on top of [LoopKit/LoopWorkspace](https://github.com/LoopKit/LoopWorkspace).

+This step is **iOS only**: GitHub Actions sync from upstream Loop, apply Glucose
+Guard icons and the display name, then publish to the existing TestFlight

+
+For a local Xcode icon/name refresh after an upstream pull:
+
+```
+./Scripts/apply_glucose_guard_branding.sh
+```
+
+Or apply a local checkout of the design repo:
+
+```
+GLUCOSE_GUARD_DESIGN_PATH=/path/to/glucose-guard-design ./Scripts/apply_glucose_guard_branding.sh
+```
 
 The Loop app can be built using GitHub in a browser on any computer or using a Mac with Xcode.

+# Glucose Guard Design
+
+iOS branding for **Glucose Guard**: logo, color tokens, and Loop override app icons.
+
+Step 1 is **iOS only**. The Loop fork
+[iDustbin/LoopWorkspace](https://github.com/iDustbin/LoopWorkspace) syncs from
+[LoopKit/LoopWorkspace](https://github.com/LoopKit/LoopWorkspace). GitHub Actions
+then apply `ios/` (icons + display name) and publish to the existing TestFlight
+account.
+
+## Layout
+
+- `branding/` — logo, SVG mark, color tokens
+- `ios/` — `OverrideAssets*.xcassets` and `display_name.xcconfig`
+- `docs/step-1.md` — what ships now vs later
+
+## Apply to a local LoopWorkspace checkout
+
+From the LoopWorkspace root:
+
+```bash
+./Scripts/apply_glucose_guard_branding.sh
+```
+
+Or point at this folder:
+
+```bash
+GLUCOSE_GUARD_DESIGN_PATH=/path/to/glucose-guard-design \
+  ./Scripts/apply_glucose_guard_branding.sh
+```
+
+Until `iDustbin/glucose-guard-design` exists as its own GitHub repo, this tree
+stays bundled inside the Loop fork so TestFlight still gets the Glucose Guard icon.

+# Glucose Guard — Step 1 (iOS only)
+
+Branding source of truth for the Loop iOS fork (`iDustbin/LoopWorkspace`).
+
+## Implemented now
+
+- App name: **GlucoseGuard**
+- Robot-cross logo on brand red (`#F4333C`)
+- iOS and watchOS override app icons
+- GitHub Actions on the Loop fork pull this tree **after** syncing
+  `LoopKit/LoopWorkspace`, then Fastlane publishes to the existing TestFlight
+  account
+
+## Not in this step
+
+- Kubernetes / web dashboard
+- Live CGM, pump, or Nightscout values
+- Withings, Rex.fit, or other third-party health APIs
+- Medical-person search and dataset access requests
+- Food overview (owned by another company / designer)
+- Custom Omnipod DASH communication patches
+
+Omnipod DASH drops on newer InPlay/Atlas pods (especially iPhone 16 / 17e) are
+handled upstream. Stay synced with LoopKit so Pod Keep Alive (Loop 3.14+)
+arrives through the fork-sync workflow.
+
+## Later
+
+- Separate design repo on GitHub
+- Web/Kubernetes shell
+- CGM detail, A1C/GMI, averages
