Import always replaced everything - brands, packages, services, FAQs,
gallery - in one irreversible sweep, even if you only wanted to bring in
one part (e.g. restoring just the gallery from an old backup while
leaving today's live catalog alone).
Backend: importData() now accepts a "sections" field (JSON array of
catalog/services/faqs/gallery) and only DELETE+INSERTs the tables that
belong to selected sections; anything not selected is left completely
untouched. Tables stay grouped the way their foreign keys require
(brands -> car_models -> packages -> package_products/upgrades as one
unit, gallery_brands -> gallery_projects -> gallery_photos as another) -
importing "packages" without its models would either orphan rows or
silently rewrite unrelated ones, so the groups aren't splittable further.
Restored images are filtered to just the ones referenced by the tables
actually being imported, so deselecting the gallery means its images
aren't written to /uploads either. No sections field (older callers)
still imports everything, matching prior behavior.
Frontend: picking a file parses it client-side (file.text() + JSON.parse)
to show each section with live counts pulled straight from the file
("4 Marken, 15 Modelle, 17 Pakete"), all checked by default. The
confirmation checkbox's warning text names only what's actually
selected. If parsing fails client-side the picker just doesn't render -
the import still goes through server-side with the (safe) default of
importing everything.
Verified end-to-end against a real ~54MB export: importing only "faqs"
reverted a changed FAQ while a newly added test brand survived
untouched; importing only "catalog" right after removed that test brand
while the FAQ stayed as already restored - confirming sections are
fully independent both ways.

The existing peek animation (row nudges right and back on first load)
only demonstrated that the row moves, not how to move it - ambiguous
now that mouse-drag is gone. On non-touch devices it's paired with a
small pill ("Mit dem Mausrad blättern" / "Scroll to browse", mouse icon
flanked by chevrons) that fades in around the peek and out ~1.2s later,
floating centered over the row at a z-index above even the frontmost
coverflow card. Touch devices keep just the peek, since swiping is
already self-explanatory there. Plays once per page load, gated behind
the same reduced-motion check as the peek itself.
