All tokens with dark-mode overrides gain a private --_name counterpart in :root.
Public tokens (--color-*, --module-*, --glass-* etc.) become stable var(--_name)
references. Both dark blocks now only override compact private tokens — no more
manual two-block sync for every future colour change.
Also removes the redundant --color-surface-2 dark override (already auto-derived
via var(--neutral-50)). No visual change.
