// ── Scalable mini-icons ──────────────────────────────────────────────────────
// Small procedural glyphs (delivery markers, etc.) authored on a 1× pixel grid
// and scaled to the current font, so they stay legible on large-font layouts
// (e.g. landscape e-ink renders text at 2×). Distinct from the XBM page icons
// further down, which are fixed-size full bitmaps drawn via drawXbm().
//
// To add a mini-icon:
//   1. Draw it as ASCII-art rows, one string per row (width ≤ 8): any char
//      other than ' ' or '.' is a filled pixel. packRow() packs each string
//      into one byte at compile time, so the strings never reach flash — the
//      binary holds only the packed bytes, identical to hand-written hex.
//   2. Wrap the rows in a MINI_ICON(name, width, ...) — width and row count are
//      bundled with the data, so the draw site carries no magic numbers.
//   3. Draw it with miniIconDraw(display, x, topY, name).
// Scaling is automatic — no per-display handling needed.
//
// packRow() is written as a single-expression recursion so it stays a valid
// constant expression on any C++ standard the firmware targets (≥ C++11), not
// just the relaxed C++14 constexpr with loops. It packs up to the string's NUL
// (capped at 8 cols), so width lives once in MINI_ICON, not in every row.
constexpr uint8_t packBit(const char* s, int x) {
  return (s[x] && s[x] != ' ' && s[x] != '.') ? (uint8_t)(1u << x) : 0;
}
constexpr uint8_t packRow(const char* s, int x = 0) {
  return (!s[x] || x >= 8) ? 0 : (uint8_t)(packBit(s, x) | packRow(s, x + 1));
}

// pass a stale width/height. Built via the MINI_ICON macro below.
