Storage Helpers

fs()

function fs(?string $adapter = null): FileSystem

Use this as the standard entry point.

fs()->put(storage_dir() . '/app.log', 'ready');
$content = fs()->get(storage_dir() . '/app.log');

Pick an adapter explicitly only when needed:

$dropbox = fs('dropbox');
$local = fs('local');

Helper behavior

• no adapter passed → uses fs.default
• first call lazily imports config/fs.php
• repeated calls reuse cached wrapper per adapter name in the current process

Use configuration + service wiring for cloud OAuth/token setup, not ad hoc helper-side logic.
