Budget Tracker
Add an expense (a label and an amount), watch the running total update, and
remove entries you no longer want. Everything persists in your browser via
localStorage — no server, no account, no network calls at runtime.
This is the pilot for the wal-sh.projects tier: larger, stateful SPAs that
go beyond the single-purpose wal-sh.tools tools. Pure logic lives in
core.cljc (testable on the JVM and in the browser); the DOM adapter in
browser.cljs renders into #app-root with no framework.
The eventual feature set (envelopes, categories, recurring templates, CSV/JSON export) is captured in the project spec. This page ships the minimal slice: add, total, remove, persist.
