Timeline on a cover

Each entry is a group carrying a border-top of currentColor at 1px, and inside it a two-column row with the year at 24% and the event title at 76%. The last entry carries a border-bottom as well, so the record closes rather than trailing off. There is no core/separator anywhere: a rule inside a plate has to run the plate's full width, and Twenty Twenty-Four narrows any separator that is not is-style-wide to a centred stub.

The columns do not stack. isStackedOnMobile: false keeps the year beside its event at 390, where a stacked row would turn five one-line entries into ten and the ledger into a list. At 390 the plate is about 302px of content inside the cover's own padding, so the year column is roughly 72px, which holds four digits at the clamp() floor with room to spare.

Every entry is one line of record and nothing else: no paragraph, no link, nothing numbered, nothing asking the reader to act. It is a history, not a process, which is what separates this section from steps-ledger and steps-run.

• It ships EMPTY. No url in the block's settings, no <img>, no background-image. Our previews substitute one of our own photographs; the buyer points the block at their own media library and the composition is already set.
• minHeight is 44rem, never vh. The preview on this page sizes its frame to the pattern, so a viewport height would size the pattern to the frame and the pair would only shrink.
• dimRatio is 40, a multiple of ten, so the class core writes (has-background-dim-40) is the opacity the span actually gets. The veil is atmosphere here, not legibility: nothing is read on it in the base.
• Every text element states its own colour. Core paints cover text #fff through a zero-specificity :where() rule, and a theme's heading element style beats an inherited group colour, so the heading states its chain as explicitly as the paragraphs do.
• A short hand-off row on the theme's paper sits below the cover, so the section reads as a section of a page rather than as the page.

One axis, and it is composition. The plate is removed and the same record is set straight onto the photograph, at a wider 52rem measure with a larger heading, because without the plate the type has the whole cover to work in.

What makes it legal is the veil's opacity, and nothing else. The dimRatio goes to 80 with a contrast veil under base type, every colour stated explicitly as a chain. The veil is measured composited at its opacity over a white photograph and over a black one, at the worse of the two, so an 80% veil is a bound no image the buyer chooses can break. Below 80 the type goes back on a plate. A 50% veil with type on it passes nothing and looks fine in the one photograph you tested it against, which is the silent failure this catalogue exists to refuse.

cover-veil-record is the variation shipped rather than the fallback cover-plate-wide, because a band across the lower third would be the same relationship as the base with a different width, and taking the plate away is a different relationship: the record and the photograph share one surface instead of being laid one on the other. It is authored to the measured 80% form that cover-veil already passes at, contrast veil under base type.

• Core blocks only. No plugin, no script, no separator, no literal colour.
• The cover's element order is the 6.6 one: the overlay span, then the inner container. The 7.0 order is invalid at 6.6.
• It is not cover-plate, which is a headline and one line of lede on a plate flush with the cover's corner. This is a record of five dated entries, held off the corner so the photograph reads beside it.
