Theme - Light and Dark

VisionPlan ships with two themes: Light and Dark. There is no Auto or System-follow option in v1 - you pick one and the app stays on it until you flip the toggle.

Where the toggle lives

The theme toggle is in the top app bar as a sun / moon icon. It is not in the Settings panel. Users searching the Settings panel for "dark mode" come up empty - the control is one bar higher, always visible regardless of which screen you're on.

Tap or click the icon to flip themes. The change is immediate - the whole app switches at once.

What the toggle covers

The theme applies app-wide:

• The editor canvas (background, wall colors, fixture colors, grid)
• All dialogs (Project Edit, Settings, Print, fixture options, etc.)
• Floating panels (entity edit, fixture picker, etc.)
• The top app bar
• The project list and onboarding screens
• The Print dialog interior (the dialog itself; print output is a separate matter, see below)

There are no per-section theme overrides.

Print output is always light

Regardless of which theme you're using in the app, PDF and printed output always renders against a white paper background with dark line work. This is intentional - architectural construction documents are read on paper or in light viewers, and dark-theme line work doesn't survive that context.

If you're working in Dark theme and preview a print, expect the preview to switch to the light paper background. The dialog around the preview stays dark.

Persistence

Your theme choice persists across sessions. Close the app, reopen it, and it remembers your last choice.

Theme is app-wide, not per-mode. Unlike most other preferences, switching between Customer and Contractor mode doesn't change the theme - it stays where you set it.

When to use which

There is no "right" answer - it's preference. A few patterns worth noting:

• Dark tends to be easier on the eyes during long editing sessions, especially in low ambient light.
• Light matches the print output, so what you see on screen is closer to what comes out of the printer. Useful if you're laying out the final document and want to spot contrast issues.
• Dark can hide thin guide lines and faint snap indicators that show better against a light background. If you're doing finicky precision work, try toggling to Light momentarily.

v1 limits

• No Auto / System-follow option - your choice is sticky until you change it.
• No custom themes or color tweaks.
• No per-mode theme.

These are deliberate v1 scope decisions. The two-theme model covers the practical need without the complexity of theme authoring.
