# webgl-deploy.sh — publish an uploaded Unity WebGL build for speech.neurapy.ai.
#
# You upload each build over SFTP to:
#     /home/neurapyc/webgl/speech/Build/<version>/                     (the WebGL player)
#     /home/neurapyc/webgl/speech/ServerData/<version>/ServerData/WebGL (Addressables bundles)
# and bump scripts/latestwebglversion.txt to the version you want live (e.g. v001).
#
# This script reads that version and creates two symlinks in the Laravel public
# docroot so the build is reachable at the URLs Unity baked in:
#
#   1) Player:   https://speech.neurapy.ai/<version>/index.html
#                <- the URL a super admin pastes into Admin -> OT Provisioning.
#
#   2) Content:  https://speech.neurapy.ai/ServerData/WebGL/...
#                <- Addressables Remote.LoadPath. The build was compiled with the
#                   "WebGL_Remote" profile whose Remote.LoadPath is
#                   https://speech.neurapy.ai/ServerData/[BuildTarget] (BuildTarget =
#                   WebGL). It is VERSION-LESS, so we keep a stable current-version
#                   symlink here and re-point it on each release.
#
# Laravel serves static paths straight from public/ (its .htaccess only rewrites to
# index.php when the file/dir does NOT exist), so real dirs/symlinks under public/
# are served by Apache directly and never hit the framework.
#
# Idempotent: safe to re-run; each link is atomically re-pointed (ln -sfn). Both
# links are driven by the same version, so the player and its content stay in sync.
#
# Usage:
#     ./scripts/webgl-deploy.sh            # version from scripts/latestwebglversion.txt
#     ./scripts/webgl-deploy.sh v002       # explicit version override
