/*
 * CRC Instagram — front end.
 *
 * Two things this stylesheet is careful about.
 *
 * 1. It assumes the theme is hostile. Divi, and most themes, set list styles,
 *    image rules, button padding and box-sizing globally. Every element this
 *    plugin emits therefore states its own values rather than inheriting and
 *    hoping. The wrapper class is on every selector so nothing leaks out.
 *
 * 2. Not one layout rule is keyed to the viewport. A feed sitting in a 600px
 *    Divi column on a 1600px monitor has a wide window and a narrow box, and a
 *    viewport media query reads that exactly backwards. Column counts come from
 *    auto-fill measured against the container; the one place a real breakpoint
 *    is needed uses a container query.
 *
 * Colours are custom properties at the top so the palette can be matched to the
 * rest of the site in a handful of lines.
