/* Rendering optimisations.
 *
 * BRIEF-48 Part 4: `content-visibility: auto` was here, on the six numbered sections
 * below. It skips rendering off-screen content, which is fast — and which also means
 * anything that does not scroll the page sees NOTHING. Measured with no scrolling:
 * .personas-section, .security-section and .pricing-section each rendered zero text and
 * reported a 760px placeholder instead of their real height, so a full-page capture, a
 * link preview or a crawler screenshot showed blank areas where the product's pricing
 * and security story should be.
 *
 * `contain-intrinsic-size: 600px` was the second half of the problem: it hardcodes a
 * fake height, so the page reserves the wrong space for a section that never renders.
 *
 * Removed rather than conditioned, because there is no version of "crawlers see blank
 * sections" that is acceptable for the page that sells the product. The layout cost is
 * a few hundred milliseconds on first paint; being invisible to a search engine is not
 * a trade worth making for it.
