PERF: Eager load Theme associations in Stylesheet Manager. Before this change, calling `StyleSheet::Manager.stylesheet_details` for the first time resulted in multiple queries to the database. This is because the code was modelled in a way where each `Theme` was loaded from the database one at a time. This PR restructures the code such that it allows us to load all the theme records in a single query. It also allows us to eager load the required associations upfront. In order to achieve this, I removed the support of loading multiple themes per request. It was initially added to support user selectable theme components but the feature was never completed and abandoned because it wasn't a feature that we thought was worth building. 2021-06-15 14:57:17 +08:00			`<%- if theme_id.present? %>`

FEATURE: Native theme support This feature introduces the concept of themes. Themes are an evolution of site customizations. Themes introduce two very big conceptual changes: - A theme may include other "child themes", children can include grand children and so on. - A theme may specify a color scheme The change does away with the idea of "enabled" color schemes. It also adds a bunch of big niceties like - You can source a theme from a git repo - History for themes is much improved - You can only have a single enabled theme. Themes can be selected by users, if you opt for it. On a technical level this change comes with a whole bunch of goodies - All CSS is now compiled using a custom pipeline that uses libsass see /lib/stylesheet - There is a single pipeline for css compilation (in the past we used one for customizations and another one for the rest of the app - The stylesheet pipeline is now divorced of sprockets, there is no reliance on sprockets for CSS bundling - CSS is generated with source maps everywhere (including themes) this makes debugging much easier - Our "live reloader" is smarter and avoid a flash of unstyled content we run a file watcher in "puma" in dev so you no longer need to run rake autospec to watch for CSS changes 2017-04-12 10:52:52 -04:00			`<%= theme_lookup("head_tag") %>`

FEATURE: Implement browser update in crawler view (#12448) browser-update script does not work correctly in some very old browsers because the contents of <noscript> is not accessible in JavaScript. For these browsers, the server can display the crawler page and add the browser update notice. Simply loading the browser-update script in the crawler view is not a solution because that means all crawlers will also see it. 2021-03-22 19:41:42 +02:00			`<% if show_browser_update? %>`
