/**
 * form-base.css - Shared styles for all user-facing forms
 *
 * This stylesheet provides consistent styling modeled on the order form:
 * - Loading overlay with spinner
 * - Toolbar (sticky header)
 * - Buttons (primary, secondary, danger)
 * - Document container and page layout
 * - Form fields (inputs, selects, textareas)
 * - Progress indicator
 * - File upload components
 * - Radio/checkbox groups
 * - Tables
 * - Print styles
 *
 * Usage: Include this CSS first, then form-specific CSS for overrides
