When the resolver encounters an unresolved [[iftags]] block containing
[[module CSS]], it inserts a sentinel string (STYLE_SLOT_PREFIX + slotId)
into the styles array to preserve source order. At render time the sentinel
is replaced with the actual CSS collected from the iftags block (if the
condition matches).
A null-byte prefix ensures no collision with valid CSS content.
