/*
 * The Pro upgrade modal.
 *
 * One BEM block, no framework. Portable to any plugin: copy the folder, and if
 * the colours need to change, override the custom properties below on
 * `.pro-modal` from your own stylesheet. Nothing in here needs editing.
 *
 * Geometry is taken from the supplied design rather than reinterpreted: card
 * 550x420 at radius 45, art 389x132 flush to the top edge, four 35x37 counter
 * boxes 12px apart with their units below them, a 192x48 pill, and a plain text
 * link under it.
 *
 * SPECIFICITY, which is the thing to get right when this lands in wp-admin.
 * WordPress ships `a:active, a:focus, a:hover { color: <scheme blue> }` at
 * (0,1,1), so a bare `.pro-modal__cta` at (0,1,0) would lose and a white button
 * label would silently turn blue on hover. Every rule below is scoped under the
 * block, which buys (0,2,0), and the two anchors additionally qualify the
 * element - `a.pro-modal__cta` at (0,2,1) - which beats (0,1,1) outright. No
 * `!important` anywhere.
