Neovim version (nvim -v)

0.10.2

Operating system/version

Linux 6.11.7

Describe the bug

If I set the default width for the dashboard to a value greater than the size that the screen can be rendered in (width = 100), the plugin crashes:

Error detected while processing UIEnter Autocommands for "*":
Error executing lua callback: ...cal/share/nvim/lazy/snacks.nvim/lua/snacks/dashboard.
lua:549: table index is NaN
stack traceback:
        ...cal/share/nvim/lazy/snacks.nvim/lua/snacks/dashboard.lua:549: in function '

...s/.local/share/nvim/lazy/snacks.nvim/lua/snacks/init.lua:123>

Steps To Reproduce

1. Update the default width to 100 and quit Neovim
2. Resize the window terminal. I set the width of my terminal to half that of my computer monitor (1920x1080)
3. Start Neovim

Expected Behavior

I think dashboard.nvim resolved this by just cutting out the edges on the header when it was overflowing.

Should be fixed now. Thank you for reporting.
