Adom Theme

#!/usr/bin/env bash
# Install the Adom theme system onto this machine:
#   1. the skill (always) -> ~/.claude/skills/adom-theme/
#   2. the VS Code theme pack (when code-server is present) -> makes the five
#      "Adom ..." themes selectable in the editor. Does NOT change the active
#      theme; that stays the user's choice.
#   3. the brand fonts:
#      - JetBrains Mono + Familjen Grotesk ship IN this package (OFL 1.1).
#      - Satoshi is fetched from Fontshare's OFFICIAL servers at install time;
#        its EULA forbids re-hosting the files publicly but blesses delivery
#        from Indian Type Foundry's own servers. See fonts/satoshi/README.md.

# --- 2. the VS Code theme pack ----------------------------------------------
# The pack MUST be installed through code-server's own CLI (`--install-extension
# <vsix>`) and NOT by copying the folder into extensions/. A copied folder is
# absent from extensions/extensions.json, and code-server PRUNES unregistered
# folders on its next launch: the pack silently vanishes and the theme picker
# shows no "Adom ..." entries at all, so a settings.json asking for "Adom Studio"
# falls back to stock Light. That bug shipped in a golden image; see SKILL.md
# "Delivering the VS Code pack". Do not "simplify" this back into a cp -r.
