/* Hero -------------------------------------------------------------------- */
/* Every child rule is scoped under `.tachyone-hero` on purpose: the hero lives inside
   `.md-typeset`, where Material's `.md-typeset h1` (specificity 0-1-1) would otherwise
   outrank a bare `.tachyone-hero__title` (0-1-0) and paint the title with
   `--md-default-fg-color--light` (#0000008a on the light scheme) — nearly invisible on
   the dark hero — while also overriding its size, weight and margins. Two classes
   (0-2-0) win without `!important`. */
