TODO.md carries the remaining work with the reasoning already settled, so the
next agent does not re-derive decisions: tasks 3-6 of the versioned-rules plan,
the designed-but-unbuilt baked FX rates, the queued visual redesign, the small
residuals, and an explicit list of what only a human with a browser can check.
ARCHITECTURE.md explains the layer rules, the single-implementation fold, the
mutation pipeline's three deliberate properties, and the gotchas that each cost
a real bug — reading a deferred event.target.value, an unset BUN_PUBLIC_* var
reaching the browser, and overriding shadcn's --accent.
CLAUDE.md gains those gotchas, the dated-rule model that replaced standingRule,
the validation this project deliberately omits, and an explicit statement that
visual and offline behaviour cannot be verified in the agent environment.
