Masthead scale: display title.

The H1 reads from display_title when it is set. Everything search-facing still reads from title.

Compare this page with masthead-long-title. Both have a long title; the browser tab and OG tags are the long form on both. Only the masthead differs, because only the masthead reads display_title.

That is the split the field exists for: the long form goes where a crawler reads it, the short form goes where a person does. A long h1 buys nothing for search — the title tag is what ranks, and the two do not need to match.

Note that the length bucket follows the rendered string. This H1 is 30 characters, so it earns the full display size rather than the size its 77-character title would have taken.

• titleThe full search-facing form. Used for the <title> tag, OG tags, and journal cards. Keep the long version here — that is what it is for.
• display_titleThe short editorial H1 for the masthead only. Optional; falls back to title when empty. Set it once title runs past about fifty characters.
