The browser fallback (PR #49) sends the full 41x4096 correlation surface to plotly.js, which tries to create 327K triangles in WebGL. This causes RangeError: Array buffer allocation failed on plotly-4.1.1.min.js:2008.

Fix: downsample the code-phase axis to at most 200 bins before serializing the figure to HTML. The max value per bin is kept so the correlation peak remains visible. The PNG rendering path (tkinter) is unaffected.

The full 41x4096 correlation surface creates 327K triangles in
plotly's WebGL renderer, causing 'Array buffer allocation failed'
in plotly.js. Downsample the code-phase axis to at most 200 bins
(keeping the max value per bin to preserve peak visibility).
