Set up sticky headers in Elementor with AI

What we learned testing it

Behavior the ability descriptions do not mention.

• Settings change the live header straight away. There is no draft and no revision, and WPVibe shows no approval page for them, so the recipes write down the old values and wait for your yes first.
• A header template from Ultimate Addons for Elementor or Elementor Pro shows on every page its display rules cover, so a change to it shows on all of them. We tested an Ultimate Addons header and a page header, not an Elementor Pro one; the recipes stop if Elementor Pro's own Sticky is on, since WPVibe has not tested the two together.
• The settings go into one element: the first one on the page or template unless the AI names another. The recipes read the header first to pick its outer container or section.
• Settings the plugin does not know are dropped without an error, and that includes the tablet and phone versions of a setting (such as scroll_distance_mobile), which win on those screens. The result lists the ones it kept, and the recipes check it and point out phone and tablet values you would have to change in Elementor.
• If the header is open in the Elementor editor, saving it there later puts the old settings back. Close it without saving before the AI changes it.
• Applying settings always switches the sticky effect on, and the AI cannot switch it off this way: switch off Enable in the header's Advanced tab, under Sticky Header Effects, in Elementor.
• An effect switched off in Elementor > Sticky Header Effects > Header Effects keeps its saved setting but does nothing on the page, and the check ability still lists it. The recipes read that screen's setting first.
• When the header starts to stick, the page below moves up by the header's height. A see-through header avoids that jump, but sits on top of whatever comes first on each page.
• The demo ability publishes a header template with no display conditions, which free Elementor does not show anywhere, and its demo page is an empty draft that does not use it. The recipes work on your own header instead.
