/* A display heading followed directly by body copy needs clearance, stated once.
 *
 * Two decisions above combine into a collision. The reset zeroes every heading
 * margin (line 26), and the display steps run at line-height 1.05 — tight enough
 * that a Cormorant descender ("y" in "Privacy Policy", "p" in "flagship") spills
 * out of its own line box by ~22px at the largest step. So a heading with no gap
 * after it does not merely sit close to the next paragraph, it lands ON it: the
 * descenders cross the paragraph's first line. Six blocks across five pages hit
 * this, at both viewports.
 *
 * The tight leading is right INSIDE a multi-line headline and stays; only the
 * boundary to the next element needs room. The rule lives here, beside the reset
 * that causes it, rather than in each section's stylesheet — every section that
 * stacks eyebrow → heading → lead needs the identical clearance, and leaving it
 * to each one is what produced six independent omissions.
 *
 * 22px is measured, not chosen: it is what `.page-hero__lead` already carries
 * after the even-larger `.t-hero`, and that pair is the one heading→copy
 * boundary on the site that never collided. */
