# Mermaid diagrams — every property + both render modes, enumerating the mermaid
# type gallery.
#
#   render=native  → editable PowerPoint shapes + connectors (no browser).
#                    Supported types: flowchart / graph, sequenceDiagram.
#   render=image   → full-fidelity PNG via real mermaid.js (headless browser).
#                    Covers EVERY mermaid type; source stamped into alt-text.
#   render=auto    → (default) image when a browser is present, else native.
#
# A diagram is an ADD-ONLY synthesizer (like 'equation'): no persistent 'diagram'
# node — the whole picture is ONE object and Add returns its path. Native mode →
# a group of editable shapes+connectors (/slide[N]/group[K]); image mode → a
# single PNG picture (/slide[N]/picture[K]). Both are addressable/movable as a unit.
#
# Source props are interchangeable — mermaid= (canonical), text=, dsl=, or src=
# (a .mmd file). Placement props x/y/width/height define a box the diagram is
# fitted into (aspect ratio preserved, centred in the box). poster= is deck-wide
# (see the note at the end) so it is documented, not baked into this multi-slide file.
#
# NOTE: intentionally NO `set -e` — render=image needs a headless browser
# (Chrome / Chromium / Edge); without one those slides are skipped with a clear
# message while the native slides still build.
#
# Auto-resident disabled: render=image launches a browser and can take a few
# seconds, so each add runs as its own process rather than contending for the
# resident's single command pipe. (The Python SDK twin keeps a resident — its
# client retries a busy connect, so it is safe there.)
