Layout fixes for narrow screens. The crypto, the share format and the stored record are
unchanged from v1.0.2 and v1.0.3, so there is no reason to re-do a backup: shares written by
any earlier version restore here unchanged, and shares written here read back in the older
ones.
The header no longer breaks on a phone
Below 720px the download strip and the top bar now wrap instead of squeezing: the strip's
"Download →" link drops to its own line under the message, and the origin notice moves beneath
the brand with a rule above it rather than being crushed into a sliver beside it. Both gain the
same side padding as the rest of the page.
The unsupported-browser notice is now a stop, not a warning
Opening YubiShard in a browser without the largeBlob extension — Firefox and Safari — used to
show a warning alongside the normal "keys enrolled here are tied to this hostname" line, which
read as something you could work around. It is now a single, plain statement that the browser is
not supported, naming Chrome on macOS or Windows 11.
