Variant D prototypes — corner cases

Multi-variant exploration: five sky scenarios rendered on one page. Comet speed 2.5× v1. Peak spikes rotated randomly. Stars sized by contribution count. Median threshold filters out low-activity days in dense data sets. Covers normal, heavy-daily, sparse, edge-2-peak, and moderate contributor profiles.

A — Normal contributor (seed 124, ~50% days active, 7 peaks)

MonWedFri
Contribution activity — normal contributor Night-sky grid, ~50% days active, seven peak days highlighted in gold, animated comet tracing them.

B — Heavy daily committer (seed 7, ~95% days active, median filters low days)

MonWedFri
Contribution activity — heavy daily committer Night-sky grid, nearly every day active; median threshold filters out low-count days so the sky stays readable.

C — Sparse pioneer (seed 303, ~8% days active, 3 peaks)

MonWedFri
Contribution activity — sparse pioneer Very sparse sky; only 3 peak days, comet still traces them.

D — Edge: exactly 2 peaks, no background (seed 99)

MonWedFri
Contribution activity — minimum viable: 2 peaks only Edge case: only two contribution days, comet sweeps between them.

E — Moderate user (seed 55, ~20% days active, 5 peaks)

MonWedFri
Contribution activity — moderate user Night-sky grid with ~20% active days and 5 peak moments.
