shinyglass is a theme layer, not a universal skin. It targets Bootstrap 5 / bslib surfaces first, then overlays denser dashboard stacks where practical.

Support matrix (as of 0.2)

Stack	Status	Notes
`fluidPage` / `navbarPage`	Supported	Drop-in `theme = glass_theme()`
bslib `page_navbar` / `nav_menu`	Supported	See `chrome-kitchen-sink.R`
bslib `page_sidebar` / `layout_sidebar`	Supported	Floating glass sidebar; nested layouts stay in-flow (0.1.1+)
bslib cards, value boxes, navsets, accordion	Supported	Tooltip / popover / toast use the glass menu surface
DT	Supported	Visible `.page-link` chips (not li-only)
reactable	Supported	Avoids double-framing the html-output
gt	Supported	Table / heading / stripe / summary chrome
leaflet	Supported	Map container transparency
plotly	Good	Glass frame + modebar; set `paper_bgcolor` transparent in R for best dark
shinyWidgets (common inputs)	Good	Slider tooltips / noUiSlider chips
shinydashboard / bs4Dash / shinydashboardPlus	Overlay	Glass header/sidebar/boxes/controlbar/dropdowns; layout stays AdminLTE
teal	Good	Use `options(teal.bs_theme = glass_theme())`
waiter / shinybusy / loaders	Good	Blurred overlays, not solid white scrims
shinyalert / SweetAlert2	Good	Popup uses glass menu surface
rhandsontable	Partial	Frame + cell ink; core grid still third-party
echarts4r / highcharter / apex	Partial	Host wrapper glass; chart internals set in R
Bootstrap 3-only apps	Limited	Theme is BS5 via bslib

Layout contract

Open bslib sidebars reserve space in main so content is not buried under the floating chrome.
Nested layout_sidebar() does not double-float.
AdminLTE left sidebars keep fixed AdminLTE geometry; glass is visual overlay only.

Examples

# overlays: datepicker, notifications, showModal, accordion, navbar menu
shiny::runApp(system.file("examples", "chrome-kitchen-sink.R", package = "shinyglass"))

# plotly + gt (+ waiter if installed)
shiny::runApp(system.file("examples", "plotly-gt-demo.R", package = "shinyglass"))

# denser AdminLTE (requires shinydashboardPlus)
shiny::runApp(system.file("examples", "shinydashboardPlus-glass-demo.R", package = "shinyglass"))

Rscript inst/scripts/audit-glass-contrast.R --apps=demo,dashboard,inputs,plotly_gt,chrome

Tips

Prefer bslib page functions when you can — glass was designed around them.
For plotly dark mode, pass transparent paper_bgcolor / plot_bgcolor in layout() (see plotly-gt-demo.R); CSS handles the modebar.
For dark mode in dense AdminLTE apps, re-check value/info box contrast after switching preset at runtime.
preset = "auto" is ideal for demos; pin "light" or "dark" for screenshots and tests.
