The post-Option-D screenshot showed Terminal cards correctly but a green felt play surface — the chrome migration only retuned in-engine constants, leaving the on-disk PNGs at assets/backgrounds/bg_*.png as the legacy felt textures. Adds solitaire_engine/examples/background_generator.rs following the same regeneratable pattern as card_face_generator. Five solid near-black variants from the base16-eighties palette: - bg_0: #151515 (Terminal canonical, BG_PRIMARY) - bg_1: #0a0a0a (BG_DEEPEST) - bg_2: #1a1a1a (BG_ELEVATED — same as card face) - bg_3: #121820 (slight cool tint) - bg_4: #201812 (slight warm tint) Per design-system.md the Terminal play surface is *flat* — no felt, no gradient — so all 5 slots are pure solid colours. Each PNG is 120 × 168 (matches the legacy tile size; spawn_background stretches to window_size * 2.0 at runtime so source resolution is immaterial). On-disk weight drops from ~16KB average to ~100 bytes per tile. Run with: cargo run --example background_generator --release Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

//! Table-background generator — writes 5 Terminal-aesthetic solid-colour
|
||
//! PNGs into `assets/backgrounds/`.
|
||
//!
|
||
//! Run with:
|
||
//!
|
||
//! ```sh
|
||
//! cargo run --example background_generator --release
|
||
//! ```
|
||
//!
|
||
//! The play-surface fill is `Settings::selected_background`-indexed
|
||
//! into `assets/backgrounds/bg_{0..4}.png` by
|
||
//! `table_plugin::load_background_images`. Per `design-system.md` the
|
||
//! Terminal play surface is *flat* — no felt texture, no gradient —
|
||
//! so all five slots are simple solid colours from the base16-eighties
|
||
//! palette, each visually distinct enough for the picker but all on
|
||
//! brand.
|
||
//!
|
||
//! Output is small (a 120 × 168 PNG with one solid colour compresses
|
||
//! to ≈100 bytes) and stretched to `window_size * 2.0` at runtime by
|
||
//! `table_plugin::spawn_background`, so the source resolution is
|
||
//! immaterial — keeping it 120 × 168 preserves the legacy tile size.
