Built with JavaScript Modules

The entire calculation engine is split into focused, reusable ES modules. This is how real productivity tools are architected.

Core Modules
  • geometry.js — Area calculations (walls, ceilings, openings)
  • coverage.js — Paint volume, presets, waste factor
  • cost.js — Paint + labor pricing
  • time.js — Realistic time estimates with productivity rates
Architecture Modules
  • project.js — Aggregates surfaces + runs the full pipeline
  • ui.js — Pure DOM update functions
  • storage.js — localStorage persistence
  • main.js — Wires everything together
All logic is pure and importable — easy to test or reuse in other tools.
