Skin:Timeless/pl

Skin based on Winter and an attempt to incorporate all the sensible things suggested on this 2015 Village pump discussion into a skin. Shh. Don't tell them. They thought I wasn't serious.

Timeless highly supports responsive web design and is optimized for a multitude of screen widths ranging from narrow mobile phone screens up to wide monitors.

The general aim is to make a fully featured skin that emphasises both content and editing tools, with multiple view modes for showing everything, focusing only on content (winter), or switching to dark/night viewing. One day it will actually do this.

Configuration
The following are only supported in MediaWiki 1.34+


 * (string, default 'cat.svg')
 * Set it as you would $wgLogo to an appropriate background image. Recommendation is an svg set to 500-750px wide: svg for HiDPI support; the size can really be whatever, but where that will result in a similar behind-content look as with the default cat.
 * For a background to potentially also work unmodified with other background-colour themes if and when they are later implemented, a transparent single-colour image is recommended, with 20-50% opacity black/white, where the alpha values of the b/w parts are likewise around 10-50/255, as this should allow it to work on most anything that isn't pure white/black.
 * Examples (which actually don't follow the above recommendation and thus probably won't work on dark backgrounds): Timeless backdrop (wiktionary).svg and Timeless backdrop (metawiki).svg


 * (null|string|array, default null)
 * Special logo rendering, allowing for custom logos for Timeless specifically (such as a square logo version without the wordmark in order to avoid duplication with the header). Also provides slightly better HiDPI support than using $wgLogoHD, as that only works for 135x135px logos, and scales all high-res logos down to this size.
 * Can be used to point Timeless at a File uploaded onwiki (remember to protect the file if using this) simply by providing the file name, or you can specify the logo path details manually using an array.
 * To reuse a $wgLogo and $wgLogoHD already set for a nominally 160x160px logo, but where the HD versions also come out the right size:
 * To use File:Cows.svg uploaded onwiki:
 * Note that uploaded logos work best as svgs or as 2x- or higher-sized rasters, and will be scaled down for each target resolution. Obviously this approach requires file uploads and thumbnailing to be enabled.
 * Recommended nominal sizes probably around 135px to 165px.

 * Recommended nominal sizes probably around 135px to 165px.


 * (null|string|array, default null)
 * To use an image instead of the default Linux Libertine serif text for the header banner wordmark. Same usage approach as $wgTimelessLogo.
 * So the english Wikipedia might use Wikipedia wordmark.svg, like so:
 * Or specify an array of each resolution version, plus the dimensions, per above (more likely with them, frankly).
 * If not using an uploaded file onwiki, specifying the dimensions is required.
 * Recommended nominal size up to 200px wide by 38px tall.
