How it plays. You run one telescope for three nights. Each night
offers a dozen observation windows, each with a time span and a science
value. Pick a set of non-overlapping windows — the telescope can
only look at one target at a time — then Lock night to bank it.
Windows that touch exactly at an endpoint do not overlap.
score per night = round(1000 × your value ÷ exact optimum)
The optimum is exact weighted interval scheduling: sort by end time, DP over compatible predecessors, computed in your browser and revealed when you lock the night.
final score = sum of the 3 night scores (max 3000).
Every player gets the same three nights (fixed seeds) — fair leaderboards.
