Keep session intensity in sync with glass_intensity_slider() — observe_glass

The slider already updates glass live on the client. This observer optionally echoes the value through update_glass_theme() so other clients / server state stay aligned.

Usage

observe_glass_intensity(input, session, inputId = "glass_intensity")

Arguments

input: The server input object.
session: A Shiny session object.
inputId: Input id of the intensity slider.

Value

An shiny::observeEvent() observer (invisibly).
