The tone paints the ground. The photograph is the overlay at 0.16, so the tint is --bg and follows the skin.
--bg
Copy left, the right half deliberately empty so the photograph has somewhere to be.
Same pattern, mirrored. A copy-position axis, not a second section.
The same mechanism on a light tone. Dark is the common choice, not the only one.
No overlay on the section at all. The pane carries the copy, so the image stays sharp — and it now has vertical padding.
When the photograph is the thing being sold, do not abstract it — put the copy on solid ground beside it.
Identical to A, plus attachment: fixed on the overlay. A control, not a section.
attachment: fixed
The overlay group has no slideshow type, so the gallery goes on the base and the tint on the overlay — as var(--bg), still palette-driven.
