/* hub.css — styling for the static hub-links block that
 * scripts/inject-hub-links.mjs writes into the homepage, the 12 city hubs, the
 * 81 suburb hubs and the 22 chain hubs.
 *
 * The block exists so those links are real HTML rather than something only
 * JavaScript can reach. The first version of it shipped with no stylesheet at
 * all, so it rendered as a bare <ul> — on the Johannesburg page, 88 links in a
 * single vertical column. This file exists so that cannot happen again.
 *
 * Structure comes from Bulma 0.9.4, which every one of these pages already
 * loads. Only the handful of properties Bulma cannot reach live here, to match
 * the .suburb-card idiom in cities.css:
 *
 *   property      .suburb-card        Bulma .card
 *   border-radius 10px                .25rem (4px)
 *   padding       1rem 1.25rem       1.5rem (card-content)
 *   border        1px #e8e8e8         0 0 0 1px rgba(10,10,10,.02)
 *   hover         (see below)        none at all
 *
 * On hover: the site had four different treatments. .card's translateY(-5px)
 * lift is used on 103 pages via gauteng.js, suburb-directory.js and
 * company-directory.js, so it is the house idiom and the one used here. The
 * border-and-shadow-only treatments on .suburb-card and .box.h-100 are not
 * replicated; a directional lift reads as "pickable", which is what a tile of
 * links needs.
 *
 * The count chip uses .tag.has-background-success-light rather than a colour
 * modifier, because .tag has no is-* colour modifiers in 0.9.4.
 * has-background-success resolves to #48c78e, the same green the rest of the
 * site uses.
