Description

Describe the problem

The navbar styling of Lumen from bootswatch is not consistent with the expected navbar: https://bootswatch.com/lumen/. For other themes the output is as expected.

library(bslib)

ui <- page_navbar(
  theme = bs_theme(bg = "black", fg = "white"),
  nav_panel("Dashboard",
            sidebarLayout(
              sidebarPanel(
                h3("Sidebar"),
                p("Sidebar content goes here."),
                actionButton("btn1", "Action 1"),
                actionButton("btn2", "Action 2", class = "btn-primary")

Research direction

Run the supplied page_navbar() example with bs_theme() and compare the Lumen navbar against the Bootswatch Lumen reference. Trace the generated styling from this entry point and verify the result across the affected navbar states; done means Lumen matches the expected navbar styling without regressing other themes.
