Tooltips for the MediaWiki module - each one explains what BELONGS in the field: what kind of value, in what format, with a concrete example, and where it ends up on Commons.
The Wikidata fields got the most attention. depicts says to enter the shown person's item, that names can be typed and picked from the live suggestions, and that the field is required unless the override below gives a reason. "Created during" warns to take the specific edition ("Berlinale 2026"), not the series. The structured license and copyright fields finally explain their cryptic defaults: Q18199165 is CC BY-SA 4.0 and must match the license template; Q73566113 means "copyrighted" and is right for own photographs.
The row labels carry the same texts - someone wondering what "P180" means points at the label, not the input. All texts exist in all five UI languages.
Why this stays uncluttered: nothing was added to the layout and nothing moved - no info icons, no help buttons, no extra rows. A tooltip occupies zero pixels until the pointer rests on a field and disappears on the first movement.
