I've completed the backend using Breeze/Vue/Inertia and it runs from resources/views/app.blade.php
For the frontend, if I just send the landing to page welcome.blade.php and then manually add more blade files to resources/views will this function properly?
Any thoughts?
Does inertia intercept requests and may prevent normal blade functionality?
If I understood correctly what you're saying, no, inertia doesn't intercept. Which route is rendered is up to the router to decide, you must define it in routes/api.php or routes/web.php.
You encounter problems if you're using vue-router tough, as it may not make a new request to the backend, depending on how you set it up
