Hero, two covers

This is the one thing to know before the buyer starts. The pattern holds two covers, and it only works when they are two DIFFERENT photographs: one that can carry a plate over its corner and one that is worth looking at with nothing on it at all. The preview substitutes two different stills for exactly that reason. Both covers ship EMPTY, which is valid at WordPress 6.6 and 7.0; click each one and choose an image, and the focal-point tool does the rest.

Every word in this pattern is on the plate, whose ground is a base chain and whose type is a contrast chain, so the contrast is measured as an ordinary guaranteed pair rather than as type on an image. A photograph's luminance is unknowable and the buyer swaps it anyway; the veil over both frames is decoration and may recede without loss.

Sized by padding only. A core/button with a typography attribute is valid at 7.0 and marked "unexpected or invalid content" in the 6.6 editor, and nothing about the render gives it away.

Core stacks the columns, so the two frames become two full-width bands. In the base the loaded frame is first in source order, which is what a phone should open with. In Loaded right the empty frame comes first, which is the ordinary picture-then-text order on a phone and is the price of the mirror; the mirror is a desktop composition and it says so.

• Loaded right (covers-swapped): the composition mirrors. The loaded frame becomes the right one, its plate moves to the bottom-right corner through contentPosition: "bottom right" and a constrained wrapper with justifyContent: right, and the empty frame opens the row. One axis: composition. Colour and type are untouched.
• Ink plate (ink-plate): the colour move on its own, by inversion. The plate becomes contrast ground with base type, and the button inverts with it so it stays legible on the new ground. Inversion between base and contrast is the only colour move that arrives in every theme; base-2 is plain white in both Twenty Twenty-Four and Twenty Twenty-Five. The frames, the veil and the layout are identical to the base.

Two full-bleed frames on their own fill the preview on this page edge to edge, and on a buyer's page the opening is never alone. So the pattern ships with what comes next: a short row on your theme's paper under the frames, a tracked label at a fixed 12rem and one paragraph at a 34rem measure, in a wrapping flex row so the label does not break in two on a phone. It is ordinary page copy and it is the first thing a buyer rewrites or deletes.

The frames are full-bleed and the hand-off row below them is a constrained band at 1240px, so the two are sized by different things: past about 1350 the band stops filling the window and starts centring its column, while a contentPosition plate goes on being positioned against the cover's own full-bleed edge. Measured at 1280 and 1920 in Twenty Twenty-Five, the plate's text and the hand-off copy started 250px further apart at the wider window; mirrored in Loaded right, where the plate is pinned to the opposite page edge and the row is not, the drift was 353px, the largest in the catalogue.

The fix is on the loaded cover only, as padding-left: max(0rem, min(100%, 50vw) + 0.5rem - 660px) (padding-right in the mirror). 660px is the band's half-column, 620px, plus the plate's own 2.5rem padding, and the 0.5rem is half the gutter, so the plate's text lands on the same column edge the copy below it does. It is 0 at and below 1280, which is the width this catalogue is authored at, so nothing about the 1280 rendering moves and the plate is still flush into the frame's corner there; the min(100%, 50vw) term keeps it 0 below 782 as well, where core stacks the columns and 100% becomes the whole page. No CSS, no class: it is one length on one block, and a theme that never gets that wide never sees it.

minHeight is 32rem, never a vh value. The preview on this page sizes its frame to the pattern, and a viewport-relative height would size the pattern to the frame in turn, a loop that only ever shrinks.

The cover's markup was checked at both WordPress versions: the 6.6 element order the two covers are authored in, the has-background-dim-30 class that a dimRatio of 30 emits, and isUserOverlayColor. Columns-level verticalAlignment is deliberately absent here: it does nothing on the front end, and with two frames of equal height there is nothing to align.
