glide:data_url fails without a full glide image cache

[rikh42]

When running the static site generator, glide images are generated directly in storage/app/static/...., but glide:data_url attempts to read the generated image from storage/statamic/glide.

If you have been viewing the site in a local browser, the cached images will coincidently be present in storage/statamic/glide, creating the illusion that glide:data_url is working. However, if the glide cache is cleared prior to running php please ssg:generate, then errors will be produced and the data urls will be blank.

I added some logging to the filesystem to report every file read and write. Here is an extract from an example project showing the write and following read from different paths.

[2025-07-07 09:57:49] local.INFO: Write File ["/Users/me/dev/clients/example.co.uk/storage/app/static/img/containers/assets/design/logo-design.png/24f5efe8bef890830bfe16b2d1cba72d/logo-design.webp"] 
[2025-07-07 09:57:49] local.INFO: read file ["/Users/me/dev/clients/example.co.uk/storage/statamic/glide/containers/assets/design/logo-design.png/24f5efe8bef890830bfe16b2d1cba72d/logo-design.webp"] 
[2025-07-07 09:57:49] local.ERROR: Unable to read file from location: containers/assets/design/logo-design.png/24f5efe8bef890830bfe16b2d1cba72d/logo-design.webp.  

Steps to reproduce.

1. Add a {{ glide:data_url }} tag to an antlers view
2. php please glide:clear
3. php please ssg:generate
4. Notice that there is no data url in the generated html files
5. Notice the error 'Unable to read file from location: ' in the Laravel log file
