# ============================================================
# orbit lab theme (fleet UI ladder rung 1 — dynamics#20)
# ============================================================
#
# Named palette for the orbit-lab window, mapped onto lib/ui's theme
# table. Pattern copied from DeslanStudio src/client/theme.eigs:
#
# orbit_theme_apply overlays this palette onto the ACTIVE theme dict in
# place, field by field. That is BY DESIGN, not a workaround — do not
# "simplify" it to `set_theme of (_orbit_theme_table of [])`.
#
# The table below is a PARTIAL override: colour keys only. A full lib/ui
# theme also carries the sizing and shade keys the renderers and the
# layout engine read — font_scale, char_w/char_h, padding, border_width,
# radius/radius_sm/radius_lg, hover_shade, pressed_shade. set_theme
# REPLACES the theme wholesale, so handing it this table nulls every one
# of those and every renderer reading them breaks. The in-place loop
# keeps the defaults and changes only the colours.
#
# Call orbit_theme_apply BEFORE constructing widgets: several widget
# constructors bake theme colours into the widget dict at construction
# time.
#
# The plot surface (the phase-portrait canvas in orbit.eigs) is
# canvas-drawn; it reads its colours from OL_COLORS below (the plot_*
# keys), so the whole window — chrome and plot — is themed from this
# one module.
