Full site editing isn’t an experimental Gutenberg feature anymore. For this to work, the theme must be a block-based theme, which basically means that it has to adhere to a specific folder/file structure. Are there any tutorials or extensions for Sage 9 or 10 to add block-based theme support to these? I tried to use an
index.html with the special comments, but the page just renders as-is, without any markup. Are there paths/blade loaders to be adusted?

experimental-theme.json also must be in place (even just an empty JSON object).
I just noticed that they still call it “experimental”, despite it not being an opt-in Gutenberg experiment.
