Grid Calibration

Nightfall settled over the balcony railing, revealing a distinct rhythmic pulse of streetlamps along the distant avenue below. I climbed atop the broad concrete ledge, bracing against the cool metal bar. Facing outward, I held a clean, transparent plastic protractor discarded in a nearby outdoor shelf against the dark horizon. Aligning its flat baseline flush with the railing's painted surface, I sighted three amber streetlights through the marked degree arcs. Each light source intersected a precise degree mark on the gauge. After validating the spatial bearings across the dark quadrant, I set the tool flat against the railing base.
