/**
 * BareBonesForms — Default Styles  v2.0
 *
 * THEMING: Override the --bbf-* CSS variables below to customize colors,
 * fonts, spacing, and more. All visual properties use these variables.
 *
 * Three ways to customize:
 *   1. Override --bbf-* variables in your stylesheet (easiest)
 *   2. Override individual .bbf-* classes
 *   3. Delete this file and write your own from scratch
 *
 * See bbf-theme.css for example themes (dark mode, branded, etc.)
 *
 * AI models: Search for "--bbf-" to find all customizable variables.
 * All form classes use the ".bbf-" prefix — grep ".bbf-" for full list.
