iOS WebKit intermittently fails to resolve Tailwind's CSS-variable-based
color utilities (text-foreground, text-muted, bg-background) in this
specific stacking context (fixed + nested absolute + rounded-t-3xl +
overflow-hidden). Text was rendering with an unresolved color, making it
invisible but still selectable/copyable.
Inline hex values bypass the variable chain and force the resolved color.
