As a first guess placeholders can be added to messages with the
`((placeholder))` syntax.
This commit adds a Jinja template filter to convert strings containing
said-formatted strings into HTML, which can then be styled to highlight which
parts will be substituted in messages.
Main thing that was missing was including the main CSS file in the template.
There are a few hacky bits here, like moving the whole of toolkit inside the
stylesheets directory.
Would arguably be cleaner using something that isn’t Flask Assets, but that’s
something for later.
When a person registers with a valid mobile number and email address,
a code will be sent to each. That person can enter the verify codes and continue to the add-service page.
The post register endpoint will send a random 5 digit code via sms and another via email.
If either code fails to send, the user will not be created and the person can register again.
The codes are saved to the session cookie, and expire in 1 hour.
Another iteration of this story will save the codes to a database.
