/* --- Section heading hierarchy -------------------------------------------
 *
 * Goals:
 *   - Every heading level is noticeably larger than its body text.
 *   - Higher-level headings are progressively larger than lower ones.
 *   - H1 is prominent but not oversized.
 *   - Lower-level headings (H4-H6) are bold/italic so they still read as
 *     headings even though their absolute size is smaller.
 *
 * Base body text in .md-typeset is 0.8 rem (~12.8 px).
 * The scale below keeps every heading clearly above that baseline while
 * maintaining a visible step between adjacent levels.
