It's unclear what device attestation does here. You can print a fake check and take whatever picture you want. If it's using dead pixels or something as a device fingerprint, you get those dead pixels. You can also fake dead pixels, of course. Authenticating the phone's OS doesn't authenticate the camera, or what the camera's looking at. It's a signal, maybe, but the weak link in "a napkin with the right numbers and scribble on it is a money transfer" is probably not whether someone has root on the device that's taking a picture of the napkin.
Are you saying they should always be present? Or only when the condition takes multiple lines; i.e. do you take issue with the ifs in zone_name_pref too?
Personally I think the indentation does a good enough job here.
Easy is almost an understatement; it's Alt+Hyphen. [Edit: My bad that's en-dash, can't tell the difference in this monospaced text field. Em-dash you have to hold shift.]
I guess on Windows it's Alt+0,1,5,1 on a numpad. Or you copy+paste from Character Map.
Generally spaces around em-dashes is a question of style, not pre- or pro-scribed by any specific typographical rule. One nice middle ground is a hair space ( ), although it’s a pain to insert.

Writing and publishing style guides like Hart's Rules (Oxford Style Guide) & Chicago manual of style have the 'em' dash use as a parenthetical closed or "no spaces" dash.
In British use – Hart's Rules – writers will choose the 'en' dash with spaces as a parenthetical dash, where US writers/publishers choose the closed 'em' dash for the same thing.
Imo, there is a conflation of 'en' dash and 'em' dash going around due to the ease of smart-dashes auto-correction turning (--) into 'em' dash with the 'en' dash and non-auto-correct 'em' dash needing a key-combo.
Common everyday typing online, I think people will simply use what is convenient and "good enough" -- a single hyphen dash as an 'en' dash or 2-hyphen dashes that may or may not auto correct into an 'em' dash. I prefer mixing spaces with a 2-hyphen dash 'em' dash, but I'm not a published writer so I enjoy doing wild things like that
I configured my Markdown renderer to replace ` -- ` with " — ". Hopefully those narrow spaces make it through HN's rendering — it's much easier when your tooling can do the job for you.
Or you've had WinCompose installed for years and type Compose+hyphen+hyphen+hyphen. — is easy to type that way. The same works for Linux with a compose key enabled, WinCompose is a program to give Windows a compose key, and comes with default sequences including those found by default in most distro's XCompose list.
I was convinced Firefox didn't support rendering partial HTML at all, but it turns out it just waits for two separate chunks to arrive before rendering. Queer.
If they are suitably random then this scheme seems to check out, but you're going to need some barbed wire and some inspiration from these https://en.wikipedia.org/wiki/Long-term_nuclear_waste_warnin... on anything that can generate v7 IDs.
