[BUG] Floating window does not respect background style

[janderland]

Bug Description

When using the normal window, the background color of the window is the same as other windows. When using the floating window, the background color is black. Other plugins (like Telescope) use floating windows which have the same background as other windows. I think this plugin should do the same.

Steps To Reproduce

1. Configure the plugin to use a floating window.
2. Open the Claude window.

Expected Behavior

The newly opened floating window should have the same background as the other windows.

Environment

• OS: MacOS 15.6
• Neovim version: NVIM v0.11.3
• Claude Code CLI version: 1.0.83 (Claude Code)
• Plugin version or commit hash: main branch as of 25-08-16.

Plugin Configuration

-- Your Claude-Code.nvim configuration here
require("claude-code").setup({
  window = { position = "float" }
})
