What it shows on the island

From holidays.yml:

Tiny chalkboard with pi and pie slice.

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

 #F5E8C8,  #7A4A2A,  #A9C9E0

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

Fixed date — no computation; the HOLIDAY_KIND_FIXED dispatch in holidayForDate compares month and day directly. See Date-algorithm core.
