//! Card-face migration PoC — generates a Terminal-aesthetic Ace of
|
||
//! Spades to `/tmp/ace_spades_terminal.png`.
|
||
//!
|
||
//! Tracks `docs/ui-mockups/card-face-migration.md`'s recommended
|
||
//! generation pipeline (programmatic SVG via the existing
|
||
//! `usvg` + `resvg` + `tiny_skia` stack already used by
|
||
//! `solitaire_engine::assets::svg_loader`). One card is enough to
|
||
//! prove the pipeline; the next step in the migration loops the
|
||
//! same code over all 52 faces + 5 backs.
|
||
//!
|
||
//! Run with:
|
||
//!
|
||
//! ```sh
|
||
//! cargo run --example card_face_poc --release
|
||
//! ```
|
||
//!
|
||
//! The example writes the PNG to `/tmp` rather than `assets/` so a
|
||
//! human can eyeball it before committing to a deck-wide rollout.
|
||
//! When the migration lands, the generator graduates into a real
|
||
//! binary that writes into `assets/cards/`.
|
||
//!
|
||
//! What this PoC proves:
|
||
//!
|
||
//! 1. The SVG-to-PNG pipeline produces valid output for a card-shaped
|
||
//! SVG (the existing rasteriser is used for full theme atlases
|
||
//! today; this confirms it works at the per-card grain).
|
||
//! 2. The Terminal palette (`#1a1a1a` background, `#d0d0d0` foreground
|
||
//! for spade glyphs) renders correctly.
|
||
//! 3. The bundled FiraMono in `svg_loader::shared_fontdb` resolves
|
||
//! `font-family="Fira Mono"` and renders both the rank "A" and
|
||
//! the Unicode suit glyph `♠` (U+2660).
|
||
//! 4. The 8 px corner radius (per `design-system.md`) renders as a
|
||
//! rounded rect at the 256×384 output size.
|
||
//! 5. SVG `transform="rotate(180 …)"` produces the bottom-right
|
||
//! flipped suit glyph called for in the spec.
