## JavaScript
```js
(() => {
  const grid = document.getElementById('cal26Grid');
  const cells = Array.from(grid.querySelectorAll('.cal26__cell'));

  // map each real cell to its grid index for distance-based falloff
  cells.forEach((cell, i) => {
    if (cell.classList.contains('other')) return;
    cell.addEventListener('mousemove', () => {
      const col = i % 7, row = Math.floor(i / 7);
      cells.forEach((c, j) => {
        if (c.classList.contains('other') || c.classList.contains('today')) return;
        const cc = j % 7, cr = Math.floor(j / 7);
        const dist = Math.hypot(cc - col, cr - row);
        const n = c.querySelector('.cal26__n');
        // wave: closer = heavier/wider/bigger
        const f = Math.max(0, 1 - dist / 2.6);
        const w  = 200 + f * 700;       // 200 → 900
        const wd = 100 + f * 50;        // 100 → 150
        const s  = 1 + f * 0.35;        // 1 → 1.35
        n.style.setProperty('--w', w.toFixed(0));
        n.style.setProperty('--wd', wd.toFixed(0));
        n.style.setProperty('--s', s.toFixed(3));

How this works

Hyper-minimal where the numbers ARE the layout. Built on the Roboto Flex variable font — a single font file with axes for weight (100-1000), width (25-151%), optical size, slant, grade. Cursor distance from each number drives a decaying weight and width via JS handler: dates near the cursor grow fat and wide, dates far away shrink to hairline.

The effect creates a “gravitational field” where the cursor pulls typography toward it. Zero decoration, zero borders, zero backgrounds — the type itself is the calendar.

Modern variable font capability turns typography from static to interactive.

Make it yours

  • Change the base font from Roboto Flex to another variable font (Fraunces, Inter, Recursive, Manrope) — each has different axes.
  • Tune the pull radius — how far from the cursor the effect reaches.
  • Adjust weight/width range mapping (default 100-900 weight, 50-150 width).
  • Add colour interpolation alongside typography — dates near cursor get accent, far dates get muted.
  • Swap the gravitational metaphor for a different one (repulsion, wave, ripple).

Gotchas — read before shipping

  • Variable fonts add file weight (~150-300KB) vs static — worth it only when using multiple axes; for a single weight, a static font is smaller.
  • The pointer-tracking handler must throttle via requestAnimationFrame or CSS font-variation-settings changes burn CPU.
  • Under prefers-reduced-motion:reduce, skip the pull effect and render dates at a fixed weight/width.
  • Variable font axes vary — check the specific font's supported axes before assuming wght + wdth exist.
  • For accessibility, ensure a fixed-typography fallback is available — the kinetic version can be disorienting for some users.
