ABC3 Categories 26.09.20.3
Base: original abc3cat 26.09.16.1 from the uploaded 20 September archive.

Changed existing files:
1. controllers/BrowseController.php
   Only loadSpacesForCategory changed. Existing live Space name, URL and short
   description take precedence over the independent business-profile snapshot.
   Empty descriptions remain empty. Deleted indexed spaces are excluded.
   No data is written back to Space or the business profile.
2. views/browse/index.php
   Logo mode uses fa-certificate instead of the picture/image alias.
3. resources/js/humhub.abc3cat.spaces-card-mode.js
   Logo mode uses the same certificate icon. Fresh server-rendered card assets
   are not overwritten by a previous PJAX visit's fallback image cache.
4. views/overrides/space/widgets/views/spaceDirectoryCard.php
   Adds an attribute identifying server-rendered cards for that cache guard.
5. module.json
   Version 26.09.20.3. All other metadata, including minimum HumHub version,
   unchanged.

All other original module files are byte-identical. No module IDs, namespaces,
variable names, styles, dependencies or database migrations were changed.
The completed ZIP has exactly one top-level module folder: abc3cat.
