 * `.ps-media-grid-fitwidth img { padding: 20px }`), and padding sits inside the border box the
 * badge is positioned against - so the badge would float out over the frame. CSS cannot read a
 * sibling's padding, so the frame thickness has to be declared once:
 *
 *     .ps-post__gallery--single { --mjwp-photo-frame: 20px; }
 *
 * Set it to whatever that padding is and the badge follows. --mjwp-photo-badge-gap is the
 * plugin's own breathing room inside the picture.

/*
 * Anchor the badge to the IMAGE, not to the container.
 *
 * On a single-photo post core scopes its `.ps-media-grid-fitwidth { position: relative }` to
 * `:not(.ps-media-grid--single)`, so in the single case there is no positioned box around the
 * image and the badge resolves against `.ps-post__gallery > a`, which is `position: relative`
 * and full container width. The image inside is `width: auto; max-width: 100%; max-height:
 * 500px; margin: 0 auto`, so anything narrower than the container gets letterboxed - and the
 * badge floats out into that empty space instead of sitting on the photo.
 *
 * Shrink-wrapping the fitwidth box to the image and re-centring it puts the image in exactly
 * the same place while giving the badge the right box to hug. fit-content follows the
 * max-height-driven width too, so tall photos work as well as wide ones.
 *
 * Scoped to our linked photos and to the single gallery: a multi-photo gallery already has a
 * correctly positioned, image-sized fitwidth box from core.
 *
 * ALIGNMENT: shrink-wrapping moves the decision here, because the image's own margins go inert
 * once its parent hugs it - and CSS cannot read them back, so this cannot be automatic.
 *
 * The default is LEFT, matching how this plugin's site aligns its photos (its theme CSS zeroes
 * the image margins that stock PeepSo sets to auto). Stock PeepSo centres instead; a site that
 * wants that sets both variables to auto:
 *
 *     .ps-post__gallery--single { --mjwp-photo-align-start: auto; --mjwp-photo-align-end: auto; }
