Long Headlines Don't Get Display Size
SHOULD: Reserve display size for short headlines — an `h1` is oversized only when ALL THREE hold: font-size >= 72px AND at least 40 characters AND >= 28% of viewport height (or >= 25% of viewport area). Keep the display size, cut the headline to its shortest true form, and let the full sentence live at 18–20px directly underneath.
Keep display type for short headlines and demote full sentences to the subhead so the fold stays usable

Why it matters
This is not an argument against big type. The detector requires ALL THREE conditions together: font-size >= 72px, at least 40 characters, and an h1 occupying >= 28% of viewport height (or >= 25% of viewport area). A punchy one- or two-word headline at 72px+ is completely fine — it is length PLUS viewport share that makes it a tell, because a 40+ character sentence at display size wraps to four or five lines and pushes the CTA, the product shot, and everything else below the fold.
Keep the display size and cut the headline to its shortest true form, then let the full sentence live at 18–20px directly underneath, where sentences read.
