# Hand-Drawn Box Label

> Wobbled rounded rectangle draws on — across the authored stroke matrix (plain/soft/sharp/spray) — or drops in and lands with a volume-true contact squash and bouncy spring recovery, with a handwritten label above or centered; boils

## Install

<InstallCommand command="npx hyperframes add hw-box-label" item="hw-box-label" />

That writes `compositions/components/hw-box-label.html`, plus 1 supporting file under `assets/fonts/`.

## Paste it into your composition

Open `compositions/components/hw-box-label.html` and copy what is inside into your own composition.

A component has no size or duration of its own. It takes both from the composition
you paste it into.

           block, the hw family runtime, the spring library, the stroke matrix,
           AND the hwWobbleRect / hwBoxBuild / hwBoxOn / hwBoxOff helpers. Size
           the wrapper over your target, then wire with positions only:

             hwBoxBuild("#hw-my-box", { seed: 3, label: "Europe" });
             hwBoxOn(tl, "#hw-my-box", 2.0); // entrance + boil per CONFIG
             hwBoxOff(tl, "#hw-my-box", 8.0);

           The levers live in CONFIG (entrance / strokeType / labelPos / boil).
           Multi-instance hosts may override per instance via hwBoxBuild opts
           using the SAME declared values (bounded identically). The helpers own
           all durations/eases internally — no raw tween args in host code.
