- the SVG artwork occupies only ~46% x 63% of its 183x183 canvas, so
the 18px render showed ~8x11px of ink; 30px roughly doubles the
visible glyph while staying under the 32px h1 line-height, so the
header row height is unchanged
- guard test asserts the inline size stays within the 24-32px budget;
SW cache v112 -> v113.
