What it shows on the island

From holidays.yml:

Compass rose on parchment map.

Sprite

Dimensions: 32 × 32 pixels. Anchored at island position (404, 284).

Added by this port via the holiday expansion. existing_sprite: null. The visual is a 32x32 transparent emblem authored by an AI sub-agent in the shared 16-color CLUT defined in scripts/holidays_art_lib.py. It overlays the island corner during the holiday’s window rather than reskinning the scene.

Palette

 #7A5A3A,  #F0E0B8,  #1A2A5E

Three-color hint from holidays.yml. This is a guide for the codegen step and the emblem authoring pass; the actual emblem samples from the shared 16-color CLUT, and the original Sierra sprites use the original game palette directly.

Algorithm

Computed by holidayNthWeekdayOfMonth(n, weekday, month, year), which calls holidayDayOfWeek (Tomohiko Sakamoto / Zeller). See Date-algorithm core.
