A graph that checks "time - late == 6" after On timer (#224) failed,
because the difference comes out as 5.999999999999972. Both values are
sums of measured frame times, and they round along different paths.
The only workaround was a Round node in front of every comparison.
- New helper nearlyEqual in values.ts. Two numbers count as equal when
|a - b| <= 1e-9 * max(1, |a|, |b|). The tolerance grows with the
size of the values, so it holds for hours of summed dt.
- Compare uses the rule for all six operators. "<" and ">" only hold
when the values are not nearly equal, "<=" and ">=" also hold when
they are. So "==" and ">" are never true at the same time.
- Equals uses the same rule when both inputs are real numbers. Objects
still compare by identity, everything else as text. The node
description says so.
- The tolerance is fixed, there is no parameter on the node. Physics
values come from float32 in Rapier and are not covered on purpose.
- The log display is unchanged and still prints the raw number.
Tests:
- ./check.sh: 156 files, 2311 tests, CHECK EXIT 0 (before 2300).
- 11 new cases in node-catalog.test.ts, including the value from the
log against 6, growth with magnitude, 6.001 != 6 and 1e-6 > 0.
- Counter-check exact compare: exactly the 8 noise cases fail.
- Counter-check "<"/">" without the exclusion: exactly 2 cases fail.
- No e2e change, the check sum stays at 1374.

PropertyValue was number | string | boolean | list. A struct joins it, which
costs two things the typechecker found rather than I did.
An object on a data edge used to mean a live entity, so asEntity would have
taken a struct for one and asString would have read .name off it. EntityHandle
now carries a symbol brand – a symbol so no field name can impersonate it, and
it never serializes, which suits a thing that exists only while the game runs.
It is built in exactly one place.
String(value) would have written a struct as [object Object] at 39 call sites.
They go through textOf(), which is identical for primitives.
normalizeGraph dropped everything but primitives from node params, so the List
node lost its value on every save ([3,1,4] round-tripped to undefined).
Variables were spared: they have a schema, params have none.
Remove comments that only restate the code, keeping the section banners
and the notes that carry a reason, a measured fact or an external
contract.
ButtonOptions.width claimed to be a fixed width but only set minWidth,
so the Graph and Texture pickers grew with the name they showed. It is
now what it promises, with a separate minWidth for the buttons that have
two forms. Narrow buttons shrink their padding, otherwise a 24px icon
button had 8px left for its glyph and truncate dropped it entirely.
__gm.labelsDropped() guards that class: the overflow guard only saw text
that was too wide, never a label truncated to nothing.

Tooling:
- Prettier as the single formatting authority (110 columns, single quotes,
measured against the existing style); Markdown excluded because table-cell
padding turns the README glossary into 1000-character lines.
- Type-aware ESLint ending in eslint-config-prettier, so a rule always means
"this is a bug", never "this looks different".
- .editorconfig and an `npm run check` that runs typecheck, lint, format and
tests in one go.
Findings fixed on the first run: three more duplicate imports, four
String(unknown) calls (parameter types narrowed instead of casts), two dead
initialisers, two redundant casts, a console.log for a real error. Two
warnings were false here and are disabled with a reason in place.
Tests 132 -> 269:
- node-catalog.test.ts covers every node with a run(), with a guard that fails
when a new node has no row.
- behavior-events.test.ts covers the ten event nodes through a running World,
checking timing rather than existence.
- Input's state machine (press/release/releaseAll) is reachable without DOM
events now; the DOM handlers are thin adapters.
Compare fell back to == without a configured operator although the schema
default is <; aligned.
