dsh-night-greeting

Late at night with only a blinking cursor on screen, dsh-night-greeting does one small thing: during a random hour between midnight and 4 a.m., it fires with roughly a one-in-a-hundred chance, throwing up a full-screen wall of text and a brief audio burst that simply says good evening, then fades away. No notification icon, no taskbar footprint, just a quiet little scare inside your browser tab.

A few design choices make the scare actually land: background tabs fully suspend polling, and the fullscreen-plus-audio sequence only fires the instant you switch back to the foreground, because the browser refuses requestFullscreen and keeps AudioContext suspended on hidden tabs; a hit that misses the night window auto-expires so you are not ambushed at 9 a.m. the next morning; and the manual trigger tool night_greeting_trigger bypasses that expiry so the demo works any time of day. Probability and time window are configurable via the profile layer with schemastery validation, so illegal values fail fast at load time rather than silently misbehaving. Zero configuration out of the box.

It is made for people who spend long evenings with DSH running and want one uninvited, gentle interruption in the monotony. No docs to read, no config files to edit, just restart the web and wait for the one percent.
