/**
 * Training Plan Generator — Tool Styles.
 *
 * All rules are scoped to #dadjogger-training-plan-generator to prevent
 * leaking into the theme or other tools.
 *
 * Uses --djt-* tokens for all colors, spacing, and typography so the tool
 * responds automatically to branding changes in the plugin admin.
 *
 * Notable unique elements:
 *   - Pace guidance grid (3-column card row)
 *   - Weekly plan cards with day rows and run type badges
 *   - Run badge color coding (easy, tempo, long, rest)
 *   - Taper and recovery week card variants
 *
 * @package DadJogger_Tools
