v0.20.30

Changed

• Desktop body font size increased from 14px to 15px (--text-base) for improved readability
• Interactive cards now show a stronger pressed state on touch (scale 0.98 + surface-3 background) instead of the barely-perceptible scale(0.99)

Fixed

• Added clarifying comment to --color-surface-2 token explaining its recessed/sunken semantics (darker than background in dark mode, not an elevation level)
