+copy_rotate_civ3_pcx_rows.py
+
+Copies the first animation row (row 0) of a Civ3-style indexed PCX sheet into
+rows 1..3, transforming each frame so the motion direction changes:
+
+- Row 1: NW -> SW  (vertical flip)
+- Row 2: NW -> NE  (horizontal flip)
+- Row 3: NW -> SE  (180° rotate)
+
+Assumes:
+- Indexed PCX (mode 'P')
+- 64 columns, 8 rows by default
+- 1-pixel border grid between slots and around the outer edge
+- Background is magenta (#ff00ff), border is (#c000ff) -- used only for sanity checks
+
+This script preserves the palette and keeps everything indexed.

+Example:

+- Reads an input FLC and decodes animation frames (supports COLOR_256, BYTE_RUN, FLI_COPY,

+- Computes which palette indices are actually used by animation frames.
+- Applies civ3_day_night palette darkening to only those used indices.
+- Preserves reserved Civ3 indices/colors (by default first 63 and last 20 indices, plus #FF00FF).

+mp4_to_civ3_sheet.py
+
+Build a Civ3-style sheet from an MP4:
+- N columns sampled by time OR by frame index
+- 8 rows (only first row contains frames)
+- Other rows magenta fill
+- SINGLE shared 1px green grid lines (no doubled borders)
+
+Output modes:
+- indexed: Civ3-style indexed palette and PCX output
+- rgb: RGB output (PCX supported; PNG also fine)
+
+Optional cutout (Option B: MOG2 background subtraction):
+- Learn a background model across the sampled frames
+- Foreground mask per frame
+- Cleanup + keep only largest blob
+- Everything else magenta
+
+Key knobs added:
+- --sample_by frame/time, with backoff handling
+- --fit crop/contain (contain avoids chopping fish at edges by letterboxing/padding)
+- --zoom (scales the frame up/down before fit; helps make subject larger in-slot)

+pcx_lights_sheet_to_civ3_flc_overlay.py
+
+Generate Civ3-compatible-ish FLC overlay animations from a Civ3-style *_lights.pcx annotation sheet.
+This script IMPORTS civ3_city_lights.py to reuse the exact glow math / palette rules.
+
+Input:  PCX sheet (ideally indexed P mode) where specific "light key" colors mark light sources.
+Output: one .flc per (row, col) cell, containing:
+        - one BYTE_RUN keyframe (not counted in header frame count; FLICster-friendly)
+        - N animation frames (LITERAL) with flicker
+        - optional ring frame
+
+Defaults: cell size 128x64
+
+Notes:
+- We render a TRANSPARENT overlay: background becomes MAGENTA (255,0,255) at palette index 255.
+- We do NOT need a base city image; this is just the glow overlay from the annotation mask.
