//! SVG builder for the Ferrous Solitaire application icon.
|
||
//!
|
||
//! Renders the project's signature `▌RS` Terminal mark (the same
|
||
//! cursor-block + monogram pair used on the splash boot-screen and
|
||
//! card backs) on a dark `#151515` background with a 1 px brick-red
|
||
//! border. Square aspect, authored in a 64-unit logical box and
|
||
//! scaled at the rasterisation site.
|
||
//!
|
||
//! Reads at every size from 16 px taskbar tile to 1024 px macOS
|
||
//! Retina icon — the high-contrast cursor block carries the
|
||
//! recognition load and the smaller `RS` letters sit beneath as
|
||
//! a secondary recognition cue.
|
||
//!
|
||
//! Same SVG-to-PNG pipeline as `card_face_svg` — `icon_generator`
|
||
//! example rasterises this at multiple target sizes and writes
|
||
//! into `assets/icon/`. The `icon_svg_pin` integration test hashes
|
||
//! rasterised RGBA bytes to guard against `usvg`/`resvg` drift.
