Sample post showing every content element

This is a sample post to check styling. Delete it once real posts exist. Most stutter isn’t slow code, it’s work landing in the wrong frame. At 60 fps the browser gives you roughly 16.7 milliseconds per frame, and style, layout, paint and compositing all want a share of that before your script runs.¹

The fix is usually to call requestAnimationFrame less, not more. Batch reads before writes and let the compositor handle anything that only changes transform or opacity.²

Default figure. Follows the text column.

Wide figure, opt-in.

Code

A normal code block:

from dataclasses import dataclass
from pathlib import Path

import numpy as np

# ~16.7 ms per frame at 60 fps
FRAME_BUDGET_MS = 1000 / 60


@dataclass(frozen=True)
class Mesh:
    """Triangle mesh loaded from a .obj file."""
    vertices: np.ndarray
    faces: np.ndarray

    @classmethod
    def load(cls, path: Path) -> "Mesh":
        verts, faces = [], []
        for line in path.read_text().splitlines():
            if line.startswith("v "):
                verts.append([float(x) for x in line.split()[1:4]])
        return cls(np.array(verts), np.array(faces, dtype=np.int32))

A wide one for long lines:

faces.append([int(i.split("/")[0]) - 1 for i in line.split()[1:4]])  # .obj indices are 1-based and may include texture/normal refs
