30+-- | This is a builder to be used on the client side. It can be run in two modes:
32+-- 1. in "hydration mode", reusing DOM nodes already in the page (as produced
33+-- by 'Reflex.Dom.Builder.Static.renderStatic')
34+-- 2. in "immediate mode", creating and appending DOM nodes as required
36+-- In "hydration mode", the preexisting DOM __must contain__ what the builder
37+-- will expect at switchover time (the time at which parity with the static
38+-- renderer is reached, and the time after which the page is "live").
40+-- For example, displaying the current time as text should be done inside
41+-- 'Reflex.Dom.Prerender.prerender' to ensure that we don't attempt to hydrate the incorrect text.
42+-- The server will prerender a text node with time A, and the client will expect
43+-- a text node with time B. Barring a miracle, time A and time B will not match,
44+-- and hydration will fail.
