A live world-time desktop wallpaper — a modern reimplementation of the classic
IBM/ThinkPad "World Time" Active Desktop wallpaper.

Credits & lineage
-----------------
- Original concept & artwork: IBM / Lenovo ThinkPad "World Time" Active Desktop
  (design lineage attributed to David Hill's ThinkPad design team).
- Open-source HTML/JS tribute (GPL): Maxim Proskurnya, "World Time Wallpaper"
  (v2.4.x), from which the city offsets used to calibrate the map projection were
  derived. <axofiber at gmail.com>

What is bundled (and its licensing)
-----------------------------------
- **Code** — GPL-2.0-or-later (see LICENSE), consistent with the GPL tribute it
  descends from.
- **Map data** — Natural Earth vector data under `worldtime/geodata/`
  (ne_110m_land, ne_110m_admin_0_countries, ne_10m_time_zones, ne_10m_geographic_lines).
  **Public domain** — https://www.naturalearthdata.com/about/terms-of-use/ .
  This is the default map (`map_style = "vector"`); it contains no IBM/Lenovo artwork.
- **Default logo** — Tux, the Linux mascot, by Larry Ewing (created with GIMP).
  See `docs/CREDITS.md` for the attribution.

What is NOT bundled
-------------------
- The **raster ThinkPad map** (`world.time.1400x1050.png`) and the **IBM/ThinkPad
  wordmark logo** (`thinkpad_logo.png`) are copyright IBM/Lenovo and are **not**
  redistributed here. `map_style = "raster"` and the ThinkPad logo therefore require
  you to supply those files yourself (e.g. from a system you own):
    - drop your 1400x1050 map at `worldtime/assets/world.time.1400x1050.png`
      (or point `base_path` at it), and
    - set `logo_path = "/path/to/your/logo.png"` in your config.
  "ThinkPad" is a Lenovo trademark; using their artwork/logo is your responsibility.
