A resource was private with no way out but the author's own Nextcloud.
Share opens reading — open, preview, download — to one person at a time by
exact email (no account is ever listed) or to everyone signed in with one
switch; what others share appears in your library marked "Shared by …".
Writing never travels: modify, re-skin, delete and the share list stay the
author's, every write still filtered on user_id, and the read routes go
through one reader rule. Rows follow the resource and the person.

A PowerPoint or Word file cannot be shown in a browser and a phone has
nowhere to open one. Preview renders the resource the way its download
would be built, turns it into one PNG per page (Gotenberg to PDF, pdftoppm
to pages), and shows the pages in an overlay that scrolls and pinch-zooms
like anything else. Rendered once per version — updated_at and theme are in
the key — and served from disk afterwards. The theme picker's sample deck
has the same Preview beside its download.
Every presentation now shows the theme picker in the library, since
markdown slides take a theme too.
