/* Safety net: anything rendered by WordPress core or a plugin that this theme hasn't
   explicitly styled (comments, shortcodes, unexpected widgets) still gets a readable
   color on the dark background instead of inheriting a light-theme default.
   Scoped under .dhacker-page / .site-footer (rather than bare tag selectors) because the
   Hostinger plugin ships a buggy admin-bar stylesheet with the unscoped selector
   ".hostinger p, h1, h2, h3, h4 { color: rgb(29,30,32) }" — h1-h4 there were clearly meant
   to be scoped under .hostinger too but aren't, so it darkens every heading site-wide for
   logged-in users. A bare "h1, h2, ..." rule here ties with theirs on specificity and can
   lose on source order; adding our own class scope reliably outranks it without !important. */
