/*
 * theme-formal — serif headlines, narrow column, hairline rules.
 * Targets FINANCIAL, LEGAL, INSURANCE, GOVERNMENT, PROFESSIONAL,
 * REAL_ESTATE, POLITICAL.
 *
 * Visual differentiators vs theme-modern:
 *   - Serif (or serif-display + sans-body) typography.
 *   - Narrower content column, single-column reading flow.
 *   - No drop shadows. Borders are hairline (1px var(--color-border)).
 *   - Hero is left-aligned with portrait-style photo split, not the
 *     hero-card visual treatment.
 *   - Services rendered as a numbered list with rules between rows
 *     rather than card grid.
 *   - Footer is a multi-column directory.
