to encompass behavior related to auto-closing and auto-reconsidering.
Note that putting this code in a single place reveals an asymmetry
between the actions:
- Auto-closing period is an optional attribute of a collection
- Auto-reconsidering period is hard-coded to 30 days for all collections
The "closing soon" bubbles were introduced in #406, and the "falling
back" bubbles in #500. However, these bubbles are part of the cached
card and so as time passes, the relative time doesn't change unless
the card is touched.
This PR introduces a stimulus controller for bubbles, which takes care
of:
- making the bubble visible during the reminder period
- calculating the relative number of days until entropy kicks in
- rendering appropriate text around the day count
