/**
 * BB Social Share - floating rail + inline rail
 *
 * Geometry and icon set follow Figma:
 * BuddyBoss-Website / node 1257:7316
 *
 *   container   padding 40px top, 8px sides, 8px bottom; column width 45px
 *   gap         12px
 *   button      48 x 48, radius 24px, 1px solid border token, no fill, no shadow
 *   icon        24 x 24 (envelope: 28px glyph clipped to 24px)
 *
 * COLOURS
 * Every colour in this file resolves through a theme.json preset token, mapped
 * once in the `.bb-share` custom-property block below. The literal after each
 * `var()` is only a fallback for contexts where global styles are not printed
 * (block editor iframe, mu-plugin on a classic theme) and mirrors the current
 * buddyboss-website palette. Change the palette in theme.json, not here.
 *
 * The only literals left in the plugin are the three brand marks (Facebook
 * blue, LinkedIn blue), which are brand assets rather than theme colour.
