The `.ref` fallback declared `--ref-color: var(--dt-primary)` AFTER every
`[data-ref='<kind>']` rule at the same specificity, so source order made it
win for any element carrying both — which is every inline reference: Bot Mode
group @mentions (agent/human/broadcast), `/skill`, `@file:`, pasted URLs.
Every kind painted the raw primary in both modes; on a dark surface that is
the thinnest colour in the palette and the reporter saw @mentions vanish.
Declare the fallback first (`.ref, [data-ref]`) so the kind rules outrank it
by order, exactly as the INLINE REFERENCES block documents. An unkinded
reference still keeps the primary link colour.
Test resolves the cascade for a real `<span class="ref" data-ref=…>` against
the compiled stylesheet (Tailwind's `@supports` color-mix fallback included).
