Turned on :error_handling, :underspecs, and :unmatched_returns in
mix.exs dialyzer config. The 97 warnings this surfaced were fixed in
place rather than suppressed:
- unmatched_return (79): explicit discard with `_ = ...` for
fire-and-forget side effects (Process.cancel_timer, :ets.new,
send/2), and pattern-matched `:ok = ...` for control-plane
Phoenix.PubSub subscribe/unsubscribe/broadcast calls so a future
return-shape change fails loud.
- contract_supertype (18): tightened @spec arg and return types on
data_builder, historical_loader, url_params, packet_utils,
encoding_utils, aprs_symbol, weather_controller, packet_replay to
match each function's actual success typing.
No behavioural change. mix compile clean, 1008 tests pass, dialyzer
count is now 0.
Replace all DaisyUI component classes with pure Tailwind CSS utility
classes following TailwindUI conventions. Use dark: variants for dark
mode instead of DaisyUI's data-theme semantic color system.
- Remove DaisyUI plugin and theme vendor files
- Configure Tailwind v4 custom dark variant for data-theme attribute
- Migrate all components: cards, tables, badges, buttons, forms,
navigation, dropdowns, modals, alerts, star ratings, spinners
- Update all auth pages (login, register, settings, password reset,
confirmation) to TailwindUI card layout
- Update content pages (about, API docs, status, packets, bad packets,
info, weather) to TailwindUI patterns
- Replace opacity-based text styling with semantic gray colors
- Update test assertions to match new class names
