docs: add light profiles guide at scripts/guides/profiles/light.py#176
Merged
Conversation
Adds a new single-page tour of every light profile available in PyAutoLens (all re-exported from PyAutoGalaxy). Mirrors the autogalaxy_workspace guide but uses al.Tracer to place lens and source bulges on distinct redshift planes and demonstrates tracer.image_2d_from for the model-instance section. Includes dedicated coverage of the newly merged SersicMultipole and GaussianMultipole profiles and a 4-Gaussian Basis (MGE) example. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Summary
Adds a new single-page tour of every light profile available in PyAutoLens (all
re-exported from PyAutoGalaxy) at
scripts/guides/profiles/light.py. Mirrors theautogalaxy_workspace version but uses
al.Tracerto place lens + source bulges ondistinct redshift planes and demonstrates
tracer.image_2d_fromfor the model-instance section. Includes dedicated coverage of the newly merged
SersicMultipoleand
GaussianMultipoleprofiles and a 4-GaussianBasis(MGE) example.Motivation: users arriving at the strong-lens modelling examples have no single
reference for what light profiles are available or how they compose into a
Tracer— this fills that gap.
Companion to PyAutoLabs/autogalaxy_workspace#85.
