I am befuddled that Twitter Bootstrap has no built-in Icon for The Cloud,
and also that Chromium's depiction of CLOUD (U+2601) has an uncanny
resemblance to PILE OF POO (U+1F4A9) when rendered small, and looks like a
looming Frankenstorm when rendered large, and not a sweet, sunny, nothing
can go wrong The Cloud.

So, I must resort to irony in my choice of icons.
They work fine. But I had to go to a lot of trouble to get Yesod to render
routes in a pure function. It may instead make more sense to have each
alert have an assocated IO action, and a single route that runs the IO
action of a given alert id. I just wish I'd realized that before the past
several hours of struggling with something Yesod really doesn't want to
allow.
