Named categories are sorted alphabetically and assigned colours from an
8-colour palette (blue, green, orange, red, purple, teal, pink, indigo).
Uncategorised bookmarks fall back to --accent-yellow (the leading UI
colour). Both the canvas dashed lines and the axis span labels (icon,
text, border, background) reflect the category colour via CSS custom
properties --bm-cat-color / --bm-cat-bg / --bm-cat-border.
