#!/usr/bin/env bash
# dots-icons-link.sh — fill the dots-icons overlay theme with symlinks into the host's own
# Tela-circle-dracula install (HyDE ships that icon theme on every GUI host).
#
# The overlay (gui/.local/share/icons/dots-icons/index.theme, searched before Tela) exists
# because Tela ships its flat tray/status icons only at fixed 16/22/24px. On a fractionally
# scaled monitor waybar asks for size×2 (44px), which falls through to Tela's coloured
# scalable/devices circles (the blue nm-applet blob). Serving Tela's 22/panel SVGs as
# Scalable keeps them flat at every size.
#
# Links, not copies: Tela-circle publishes no licence (2026-11-09), so the repo can't
# redistribute its SVGs. Each host links its own installed files instead.
#
# Usage: bin/dots-icons-link.sh [-n]   (-n = dry run). Idempotent; ./install.sh runs it on
# GUI hosts. Exit 1 if Tela is missing or any icon could not be linked — the overlay then
# degrades gracefully (Inherits=Tela-circle-dracula), so callers treat that as a warning.
