% Interactions
%  Heat and cooling
%   Contact                  Result
%   -----------------------  ---------------------------------------------
%   Oil + fire or lava       Oil ignites
%   Wood + fire or lava      Wood ignites; smoke can form above it
%   Glass + fire             Glass becomes sand, which suppresses the fire
%   Ice or snow + fire       Ice/snow melts into water; the fire goes out
%   Sand + fire              Fire goes out
%   Water + fire             Fire becomes steam; water remains
%   Ice meltwater + fire     Fire goes out during the meltwater cooldown
%   Water + lava             Contacting water and lava become stone
%                            Cooling can spread into nearby lava
%   Sand or acid + lava      Sand/acid becomes smoke
%   Glass + lava             Glass disappears; steam may form above it
%   Ice or snow + lava       Ice/snow becomes steam
%   Water + ice              Water freezes after any meltwater cooldown
%
%  Acid
%   Contact                  Result
%   -----------------------  ---------------------------------------------
%   Acid + water             Contacting cells can become steam
%   Acid + ice               Ice and contacting acid become steam
%   Acid + sand, stone,      Affected material dissolves; contacting acid
%     oil, wood, metal,      becomes smoke
%     or snow
%   Acid + fire              Fire becomes smoke
%   Acid + glass/concrete    No corrosion with the default material table
%
%  Flow, settling and lifetime
%   Water seeks level pools; oil floats above water. Denser mobile
%   materials can sink through lighter fluids. Solids form barriers.
%   Resting snow under sufficient load compacts into ice.
%   Fresh concrete absorbs adjacent water and dries sooner. Dry concrete
%   stops absorbing water; it retains its powder transport behavior.
%   Ordinary fire, steam and smoke disappear when their lifetimes end.
%
%  Particle lettering
%   Original letter particles stay fixed without aging or compacting.
%   Contact reactions and brush replacement still affect them. Changed
%   particles lose their anchors; products and fresh paint move normally.
%   Destroyed letter cells are not restored.
%
% Contact refers to an adjacent cell above, below, left or right. Reaction
% rates and material properties are adjustable in the controls below.
%
% Edit these controls, then restart. Click or Space selects the next material.
% Grid dimensions are columns/rows. A finer grid costs more and makes grains
% smaller. Hz sets numerical steps per second, not movement speed.
% FlowRate sets material transport events per second. All clocks use dt.

% Keep grid dimensions integral and at least 4, physics rate positive,
% gas/concrete lifetimes positive, radii nonnegative, bloom spread positive,
% RGB in [0,1], and the motion box inside the canvas. Zero source rate or speed
% is supported. None stops brush deposition; the spring and world keep running.
% Only a click changes material. Keep turn rates positive, response nonnegative
% and retreat in [0,1]. Chemistry is an artistic sandbox model. Disabling reactions
% also stops lifetime decay and snow compaction; sources, drainage and motion continue.
