4grayandClaude Fable 5 29499a0bae fix(release): raise width factors above every observed rendering ...

The narrow factors were themselves under-estimates. `r` was assigned 0.38
while measuring 0.389 em here and about 0.49 em in the environment that
reported it, so a 54-`r` line estimated 1067px, rendered 1381px there, and
was neither wrapped nor clamped. The guard test added in the previous
commit did not catch it only because no sample held a long narrow run.

Root cause: the SVG names `DM Sans` and nothing guarantees it is installed,
so each host resolves the fallback chain differently and renders the same
line at a different width. No estimate can be both tight and correct across
environments, so the factors now sit well above the widest observation —
every sample over-estimates by at least 1.25x locally, which covers the
wider measurements reported in review.

The guard test gains the cases that were failing (long `r` and `i` runs,
punctuation, digits) and its failure message says to raise the factors
rather than suggesting the test is wrong. The word-wrap test is rewritten
as a property — whole words, in order, each line within budget — because
pinning exact break points made every future calibration look like a
regression.

190 tests passing.
