/*
 * Gadget: mainpage — styles for markup this gadget creates.
 *
 * Nothing on the server emits an odometer: mainpage.js builds it, so a reader
 * whose browser never runs the script never needs these rules, and shipping
 * them with the script rather than with a component's TemplateStyles is what
 * lets two unrelated components — the hero statline and the event countdown —
 * share one implementation instead of each carrying a copy of it.
 *
 * Sizing is deliberately absent. A reel inherits font-size, weight and colour
 * from whatever it was built inside, which is how the same markup is a 13px
 * figure in the hero and a 3rem digit in the countdown without this file
 * knowing that either exists.

   outrank that, which would push each digit out of its 1em window and clip it. */
