Overgeared Hero: a Backpack Planner, a build on every hero page and a boss guide

Three additions for Overgeared Hero: plan a backpack layout before you spend in the shop, see each hero's own Supplies as a recommended build, and look up the counter to every enemy family.
Backpack Planner
Overgeared Hero is decided in the shop. Your hero fights on their own, and what you control is which items you buy, where they sit in the backpack and what you merge. The Backpack Planner lets you work that out without spending a Coin: place items on a grid, rotate them, and see which merges your current items open up.
The game doesn't publish a backpack size, so the planner's grid is a sandbox and says so on the page. Use it to test how shapes fit together and which merge chain you're building toward. The layout is kept in the page address, so a link shares it.
A build on every hero page
Each hero comes with Supplies, the items their kit is written around. Hero pages now show those as a recommended build at the top, with each item linked to its page and merge recipe. Nothing in that block is our opinion. It is the hero's own ability text, laid out so you can see what to look for in the shop.
Boss guide
The boss guide goes through each enemy family's mechanic and names the pet or item that answers it: what to bring against healers, against bosses that return damage with Spike, against Dodge and Stun, and against enemies immune to your main debuff. Read it when a run stalls on one enemy: the fix is often a single swap.
