My style guide or theme didn't apply

Symptoms: a screen renders as plain unstyled content, or a theme change visibly lands on some screens but not others.

Check the canvas, not the reply#

Important habit: the chat may report a theme change as done while the canvas hasn't moved. Trust the canvas. If the screens didn't change, the change didn't land, regardless of what the message said.

Fixes, in order#

1. Reload the project. A stale render is the cheapest possible explanation.
2. Re-apply the theme change in chat — and watch the screens.
3. Re-apply at project scope. If you asked for a change while focused on one screen, ask again explicitly: "Apply this theme to every screen in the project."
4. Check the screen's origin. Screens created as responsive variants, or through some import paths, have historically been the ones most likely to miss the project theme. If one specific screen is the odd one out, that's the likely cause — ask for the theme to be applied to that screen by name.

Fonts specifically#

A font can be set in the theme while the stylesheet that loads it isn't refreshed, so the design claims a font it isn't rendering. See Fonts and typography.

Don't fix it screen by screen#

Hand-recolouring each screen makes the symptom go away and guarantees drift later. Get the theme applied properly instead.

Reporting it#

Contact support with the project link, the screen name, and what you asked for. This one is fixable on our side, and specific reports are what make that possible.
