text based garden key

a x b: row x column
{a, b: c}: plant c at coordinates a, b

fb: fool's bolete
wg: wrinklegill
gr: green rot
sb: shriekbulb
tg: tidygrass
ed: everdaisy
ip: ichorpuff
ee: empty
xx: barrier
zz: any plant, if there are multiple in the same garden, they can be different unless otherwise specified.
| between tile or __x__ (underscore in markdown): trapdoor (diagonal trapdoors not implemented)
[]: null. the same as an empty tile, but doesn't contribute to tile count and plants can't mutate on these tiles.
[+]: null+. null tile but plants can mutate on it.
[zz]: zz on a null tile
{x, y, z}: x, y, z all on the same tile.
[e], [x], [z]: shorthand for [ee], [xx], [zz], respectively.
zZ: bud
m?: unknown mold/mildew bud
q?: unknown queenbeet bud
Zz: sprout
Q?: unknown queenbeet sprout
ZZ: bloom
zz: mature
!zz: decaying (for jqb this is Jqb)
qzz: quarantined zzs, each zz must be strictly greater than the degree of quarantine (for example, if it says 10 4qzz the degree of quarantine is 4) kings moves apart, can be in any configuration. these are assumed to be the only tiles.
A-Z: variables. e.g. N Mqzz means there are N M-quarantined zzs.
(A-Z): hypothetical plant. you define the rules. rules are defined by the format (tuple --> plant), for example, (4cl --> gc), or (bw, gm --> gc).

All tiles in the minimum rectangle covering all defined is assumed to be null. Everything outside the defined grid is considered "undefined". You are not able to explicitly define undefined tiles, these default to null tiles. [e] or similar can be used as a null tile, to make the format look better on discord. All gardens are assumed to have the bottom left coordinate anchored at (0, 0), and upwards is positive y, and rightwards is positive x.

for example:
[Jqb] ee CI
ee ee ee
xx jqB tG

for example:
{99, 99: tg}, {0, 3: tg}

for example:
14 Mq(A), (bw, A --> A)

for example:
[e] zz zz zz zz
[z] m? ee
ee ee ee
