/* ==========================================================================
   Mercury Mining Operations — shared theme (a11y-NEUTRAL chrome)
   Visual frame shared by BOTH trees: colours, type, layout grid, and generic
   component styling. It carries NO accessibility behaviour of its own — the
   toolkit base.css (loaded after this) provides .sr-only / :focus-visible /
   reduced-motion, and the root tree's inaccessible-overrides.css breaks them.
   Contrast here is the accessible baseline; the override file degrades it.
