/**
 * Springtime History Archive — front-end styles
 *
 * Font-family is intentionally left untouched so the parent theme's
 * typography controls headings/body text. Only color, spacing, and layout
 * are defined here.
 *
 * Palette below uses the site's actual design-system colors:
 *   Primary 500  #151F72  deep navy
 *   Primary 300  #2A7F9D  teal   (= Primary 900)
 *   Primary 700  #D95F7E  rose
 *   Secondary 100 #EEA7C9 light pink
 *   Primary 100  #2C2C2C  ink / near-black text
 *
 * Every color below is driven from the CSS variables on .stha-wrap, so
 * retinting later only means editing the :root-style block at the top.
 *
 * NOTE ON SPECIFICITY: a handful of rules below use !important. This is
 * intentional and limited to states (hover/focus/active) on the tab and
 * accordion buttons, because many themes ship global `button` styles
 * (background, border-radius) that otherwise win the cascade on hover/
 * active and make the pills snap to square or flash an unrelated color.
 * Owning those states explicitly keeps the widget's look consistent
 * regardless of which theme it's dropped into.
