- gallery thumbnails now object-fit: contain (whole image, letterboxed),
and a card links to the new detail page instead of the raw file
- /art/{id} detail page: large uncropped image, "Open full size",
"Delete" (moved here from the gallery), and "Copy image"
- clipboard Stimulus controller copies the image to the OS clipboard
(converts non-PNG via canvas) for pasting into WhatsApp etc.
