Sugar @ nucleum fragment modifier marks a fragment-shader entry on the nucleum surface.

# =============================================================================
# nucleum — sugar @ nucleum fragment modifier
# =============================================================================
#
# What this teaches:
#   • Sugar modifier — `@ nucleum fragment` on a function declaration marks
#     it as the fragment-shader entry (NucleumRole::Fragment); the parser
#     reads `fragment` as structured modifier data on the nucleum annotation,
#     never as an untyped name/argument pair
#   • The la reader spelling — `nucleum` is the la surface of the kernel
#     annotation identity; the en twin is `@ kernel fragment`
#   • A marked fragment function is a systems/shaders entry, not a host
#     entry — the plain `incipit` driver below proves the module still
#     checks and runs on the host lane
#
# Common mistakes:
#   • writing `@ fragment` alone — the bare fragment name stays the graphics
#     statement annotation, not the nucleum modifier
#   • expecting the marked function to be called from a host `incipit`
#
# See also: nucleum, annotation-sugar
