File Details
header.html looks like
<header>
<h1 class="header-title">blah</h1>
<img src=www/logo.png alt="blah-Logo" class="header-logo">
</header>
while ui.R is similar to

shiny[fluidPage, includeHTML, includeCSS, addResourcePath, tags], # not adapted
<...>
)

#' @export
ui = function() {
fluidPage(
title = 'blah',
# shiny deploys from app.R root (project)
includeHTML('www/header.html'),

runApp()Problem Detail
When running the app, www/logo.png in www/header.html cannot be found. This doesn't change when deleting the www/-prefix. However, when adding addResourcePath(prefix = 'www', directoryPath = './www') above ui() in ui.R the logo gets displayed as expected (as long as the prefix is set). I do not understand where this is in line with addResourcePath() documentation. Same holds for the styles.css.
