/*
 * Instagram Caption Generator - tool-specific styles.
 *
 * Composes the shared primitives in tools.css (.tool-form-card,
 * .mode-toggle, .text-input, .primary-btn, .results-region,
 * .tone-pills, .quota-banner, .upgrade-banner, .toasts, etc.). Only the
 * tool-specific pieces live here:
 *   - 3-tab mode-toggle overrides (the shared slide rule only handles 2)
 *   - image dropzone + thumbnail
 *   - focus-keyword live preview + brand-voice field
 *   - caption cards
 *   - the 125-char "show more" hook visualization (the headline UI)
 *   - editable Hook / Body / CTA structure breakdown
 *   - hashtag tier pills
 *
 * Brand color: yellow-500 (#eab308).
