Raises the final-stage Kanto starters to 100 base speed, halves every TM price, and re-slots the Route 1 grass table — all without copying a single record whole.

Persona: the Tweaker. A player who wants one number changed and copies an example to get there. This is the shortest complete mod in the gallery and the one to start from.

Try it

python3 tools/modkit.py validate mods/examples/example_balance_tweaks --base imported
luajit mods/examples/example_balance_tweaks/tests/example_balance_tweaks_test.lua

Then enable it: add example_balance_tweaks = true under mods in your options.lua, or toggle it in the F10 mod manager.

What it demonstrates

Seam	Where
`content.pokemon:patch`	`main.lua` — deep-merges one leaf, leaves the rest alone
`content.items:each`	`main.lua` — walks the merged view to find TMs instead of listing them
`content.encounters:patch`	`main.lua` — a list leaf replaces wholesale even inside a patch
`content.<r>:get`	`main.lua` — the guard that turns a missing id into a log line, not a crash

patch is the point. The legacy mods/example_mew_starter has to copy every field of Mew to change two sprite paths, because api 1 only had override. With patch you name the leaf:

mod.content.pokemon:patch("VENUSAUR", { baseStats = { speed = 100 } })

Everything not named — learnset, types, evolutions, spriteFront — keeps its base value, and a second mod patching baseStats.attack on the same species composes with this one instead of clobbering it.

Exact changes

VENUSAUR base speed 80 → 100
BLASTOISE base speed 78 → 100
CHARIZARD base speed 100 → 100 (already there; kept for symmetry)
every item whose machine.kind == "TM" has its price halved (TM_TOXIC 4000 → 2000, and 49 others; HMs carry machine.kind == "HM" and are left alone)
ROUTE_1 grass rate 25 → 20, slot table re-weighted to include SPEAROW

Field meanings are in the generated registry reference (modkit docs), section pokemon, items and encounters.

Base stat and mart price tables come from the player's own imported ROM; this mod ships numbers, not data.
