Modularize calculator into separate source files
- Split 3470-line iframe.html into manageable components - Created src/ directory with styles.css, template.html, calculator.js - Updated build.js to assemble from modular source files - Maintains identical functionality with improved maintainability - Single source of truth: edit in src/, run build.js to generate both outputs

* Dog Calculator Build System - PRODUCTION VERSION
|

* Dog Calculator Build System - MODULAR VERSION
|
||||
*
|
||||
* This FIXED build script generates iframe.html and dog-calculator-widget.js
|
||||
* with EXACTLY the same functionality from iframe.html as the single source of truth.
|
||||
* This build script generates iframe.html and sundog-dog-food-calculator.js
|
||||
* from modular source files in the src/ directory.
|
||||
*
|
||||
* Source files:
|
||||
* - src/styles.css - All CSS styles
|
||||
* - src/template.html - HTML structure
|
||||
* - src/calculator.js - JavaScript functionality
|
||||
*
|
||||
* Output files:
|
||||
* - iframe.html - Standalone calculator page
|
||||
* - sundog-dog-food-calculator.js - Embeddable widget
|
||||
*
|
||||
* Usage: node build.js
|
||||
*
|
||||
* ✅ WORKS CORRECTLY - Fixed the previous broken implementation
