/* ===========================================================================
   MEGALITH MEDIA — v02
   One stylesheet for the five tabs. v01's CSS grew a class per view; this one
   has a class per IDEA (card, pill, badge, empty, missing) and the views compose
   those. The test of this file: a reader should be able to tell a "we have this"
   from a "we do not have this" without reading a word.

/* ── Modal ──────────────────────────────────────────────────────────────── */
/*
 * `[hidden]` IS NOT ENOUGH ON ITS OWN.
 *
 * The `hidden` attribute works by way of the UA stylesheet's `display: none`,
 * which any author `display` declaration outranks. `.modal` sets `display: grid`
 * and `.login` sets `display: grid`, so a "hidden" modal stayed laid out, its
 * full-viewport backdrop sat over the page, and it swallowed every click —
 * including the Sign in button. Found by driving the deployed build in a browser:
 * the click timed out with "<div class="modal__backdrop"> intercepts pointer
 * events".
 *
 * This is written as a blanket rule rather than a list of the three selectors
 * that happen to be broken today, because the next component to set `display` on
 * a hidden host would reintroduce exactly this bug and it would be invisible
 * until someone tried to click through it.
