Add configurable default home screen action

Themes can now specify an initialAction in home screen config to set the default selected action when entering home normally. Falls back to this theme setting when no explicit action is requested, but explicit firmware navigation still takes precedence.

 Conversion runs the firmware repo's `lib/EpdFont/scripts/fontconvert_sdcard.py` script unmodified, so output matches a local host build.
 
+## Custom SD-card themes
+
+Downloadable themes are packaged in the tools repo under `../crosspoint-tools/public/themes/<theme-id>/`. Each theme folder must contain a `theme.json`; optional assets such as generated BMP icons live beside it, usually under `icons/`.
+
+See [SD-card theme creation](./docs/theme-creation.md) for the full JSON format, device-specific overrides, icon generation, CrossInk extension fields, and packaging rules.
+
+After adding or changing a hosted theme, regenerate the download manifest:
+
+```bash
+python3 scripts/generate-theme-manifest.py \
+  --root ../crosspoint-tools/public/themes \
+  --base-url http://crosspointreader.com/themes \
+  --output ../crosspoint-tools/public/themes/themes.json
+```
+
+The script scans every theme folder, includes every file in each package, and writes size and CRC32 values used by the device downloader. Commit changed theme package files and the regenerated `themes.json` in `crosspoint-tools`.
