Trend#percent divided the delta by the signed previous value, so a negative
base inverted the sign of the result and contradicted #direction. This showed
an up arrow next to a negative percentage (and vice versa) for anything that
can go below zero — most visibly net worth in reports and balance sparklines.
Divide by the magnitude of the base instead, and carry the sign of current
when the base is zero so an all-negative move reports -Infinity rather than
+Infinity.
Fixes#2579
Since the very first 0.1.0-alpha.1 release, we've been moving quickly to add new features to the Maybe app. In doing so, some parts of the codebase have become outdated, unnecessary, or overly-complex as a natural result of this feature prioritization.
Now that "core" Maybe is complete, we're moving into a second phase of development where we'll be working hard to improve the accuracy of existing features and build additional features on top of "core". This PR is a quick overhaul of the existing codebase aimed to:
- Establish the brand new and simplified dashboard view (pictured above)
- Establish and move towards the conventions introduced in Cursor rules and project design overview #1788
- Consolidate layouts and improve the performance of layout queries
- Organize the core models of the Maybe domain (i.e. Account::Entry, Account::Transaction, etc.) and break out specific traits of each model into dedicated concerns for better readability
- Remove stale / dead code from codebase
- Remove overly complex code paths in favor of simpler ones
