   Straps and Stories - store stylesheet
   Palette, typography and the mark are LOCKED by brand/BRAND_BRIEF.md.
   Do not add a colour here that is not oxblood, ink or cream (or a neutral
   step between them). "The product is the colour" - the identity stays
   near-neutral so a green lizard, a cognac gator and a black croc can all sit
   inside it without fighting.

   THEME RULE: every colour gets its value on bare :root first. The dark blocks
   only REDEFINE tokens. Nothing is defined for the first time inside a media
   query, so a browser that ignores the query still renders a complete page.
