Replace the pre-optimisation gas estimates with freshly measured values
after the GF256-table / uint256-grid / Yul-assembly rewrite:
Fixed mask: v1 byte ~930 k (was ~2.24 M), v5 ~3.3–3.6 M (was ~8.9 M)
Auto mask: v1 ~5.3 M, v3 ~11 M, v5 ~15.7 M (all now below 30 M limit)
SVG render: ~2.36 M for version-1 with 4-module border
Also adds a MASK_AUTO table, SVG row, and corrected scaling guide.
