/* SecDek — visual language inspired by PatDek.
 *
 * Principles:
 *   - White background, near-black text, one muted gray for metadata
 *   - Single sans-serif body; serif display for titles/section heads
 *   - Centered content column; no cards, borders, shadows, or chips
 *   - `* * *` asterisk dividers between sections
 *   - Minimal color; links are underlined in body text color
