Add the SealShare website for sealshare.nonameweb.ch

website/ is hand-written HTML and CSS, uploaded as it is, like the
MailifySMS site: SealShare as software a company installs for its own
upload platform, how it works, features, a desktop/phone and light/dark
gallery of the generated screenshots, a dated and sourced comparison with
hosted transfer services and self-hosted tools, the Docker quick start,
FAQ and a privacy page for Plausible. Colours come from the app's scheme,
Google Sans Flex is served locally, nothing else loads from other hosts.

The README shows three screenshots and no longer calls the encryption
end-to-end. WebsiteTest guards missing files, other hosts, the screenshot
set and the encryption wording.

 ## Risks and open questions
 
-- **Selecting files in the upload shot** relies on Livewire accepting `livewire-file:` references set
-  from the browser; if it does not, that shot shows the empty drop zone with options (step 4).
+- **Selecting files in the upload shot** works: the files are stored with Livewire's own
+  `FileUploadConfiguration::storeTemporaryFile()` and handed to `_finishUpload` by their signed
+  names; Livewire's temporary-upload cleanup is turned off for the run, because under the frozen
+  clock it deletes them.
 - **Comparison accuracy and fairness.** Other products change; the tables are dated and sourced,
   and re-checked when the site is updated. Swiss unfair-competition law expects comparisons to be
   accurate and not misleading — values that cannot be sourced stay "—".
