#!/usr/bin/env bash
#
# bootstrap.sh - Web-install entry point for tingle, meant to be fetched
# fresh from `main` and piped straight into bash:
#
#   curl -fsSL https://raw.githubusercontent.com/darthjee/tingle/main/install/bootstrap.sh | bash
#
# Downloads the pinned release zip (tingle-<tag>.zip) from GitHub Releases,
# unpacks it into a disposable work directory, and hands off to the
# installer shipped inside the zip (install/installer.sh).
#
# Kept deliberately small and boring: this is the only script ever run
# blindly via `curl | bash`, so its surface must stay easy to audit.
#
# Env vars:
#   TINGLE_REPO        - GitHub "owner/repo" to install from.
#                         Default: darthjee/tingle
#   TINGLE_VERSION      - Release tag to install (plain X.Y.Z, no "v" prefix).
#                         Default: pinned literal below.
#   TINGLE_ASSUME_YES  - When set (to any value), skips the y/N confirmation
#                         prompt. Meant as a one-off prefix, e.g.:
#                           TINGLE_ASSUME_YES=1 curl -fsSL ... | bash
#                         not something you export permanently.
#
# Dependencies: curl, unzip, bash.
