+## Local frame templates
+
+### Official iPad Pro frame
+
+The `frames` lane uses Apple's **iPad Pro (M5) 13-inch, Space Black, Portrait**
+PNG, available from [Apple Design Resources](https://developer.apple.com/design/resources/#product-bezels)
+in the [iPad Pro (M5) download](https://devimages-cdn.apple.com/design/resources/download/Bezel-iPad-Pro-(M5).dmg).
+
+Download and open the disk image, review its Apple Design Resources license,
+and copy `PNG/iPad Pro (M5) 13" - Space Black - Portrait.png` to:
+
+```text
+.build/frameit-assets/ipad-pro-13-m5.png
+```
+
+Alternatively pass `ipad_frame:/absolute/path/to/portrait.png` to
+`bundle exec fastlane frames`. Keep the licensed source artwork local; do not
+commit or redistribute it as a standalone asset. The lane exports composed
+Termind mockups using frameit, under Apple's design-resource usage terms.
+
+The unmodified template is 2300×3000. Its transparent screen opening is exactly
+2064×2752 at (118, 124), matching the M5 simulator at native scale. frameit rotates
+it for landscape captures and produces a 3000×2300 composition. Neither the
+screenshot nor the frame is resized. The pinned frameit library has no built-in
+M5 frame, so the lane registers this device at runtime.
+
+### MacBook Pro narrow frame
+
+Mac Overview compositions use the existing narrow-bezel MacBook Pro artwork,
+prepared locally as `.build/frameit-assets/macbook_pro_template.png`. Supply an
+alternate location with `mac_frame:/absolute/path/to/frame.png`. Keep the source
+artwork outside version control and retain its original usage terms.
+
+The prepared transparent template is 4260×2620, with a 3454×2243 screen opening
+at (403, 74). The native 3024×1964 capture scales proportionally into this opening.
+Its black full-screen camera strip remains visible at the top; no desktop or
+personal system UI is added. A missing template fails before publishing outputs.
