/* Mobile density pass 2026-08-14: headings and block spacing read as oversized
   on ~375-390px screens compared to competitors (moedelo.org, lad-salon.ru).
   Same 4 named sizes, same --spacing-unit/--spacing-section-mobile tokens —
   only the values differ below 768px, so every consumer (h1-h3, card titles,
   tariff prices, grid gaps) gets denser automatically without a 5th size or
   a second spacing scale. --text-4 (body/nav/faq/table copy) is deliberately
   untouched — it's already near the 16px readability floor.
   --text-3 lands at -25% instead of the requested ~20-25% for h1/h2: h3 is
   only 1px above --text-4 to start with (18px vs 17px), so a full 20-25% cut
   would put h3 (e.g. card/tariff titles) visually smaller than the body text
   sitting right under it in the same card. 16px keeps h3 >= body while still
   shrinking noticeably from 18px. */
