/* Social Media Links component
   Where the site is on social media, shown on a page. The addresses come from
   Settings, Social Media; presentation comes from the settings resolved in
   _SocialMediaLinks_Base.cshtml.

   Two templates share this file:
     .social-links--list   ContactList, a row per platform naming it
     .social-links--row    IconRow, the marks in a line

   Four styles, each meaning the same thing in both templates:
     plain     nothing behind the mark
     bordered  a line around it
     filled    a tinted ground behind it
     brand     the platform's own color

   The marks are Bootstrap Icons, so they take the color of the text around
   them. Everything below is chrome around that. */

/* Brand colors ------------------------------------------------------------
   The one place this file knows a platform by name. The renderer puts the key
   on the item and nothing else here depends on which platforms exist: a
   platform with no rule below simply keeps the text color, which is what every
   other style uses anyway.

   In a row the color fills the mark, which is how each of these platforms
   draws itself. In a list it colors the glyph, because a column of filled
   circles beside plain rows reads as decoration rather than as links. */
