Subject: [PATCH] revert: keep the wordmark's original letter-spacing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tightening the gaps bought letters a third taller at the same width,
which helped the hairlines — but it changed the logotype's character,
and the shop prefers the drawing as it was designed. The logo returns to
260x36 with its spacing intact.

The threshold fix that made the A's diagonal survive stays: that was a
separate problem and it is still solved.

lib/brand/tighten.ts and `npm run brand:variants` are kept rather than
deleted. Both are tested, the variants script is also how the threshold
itself was chosen, and a spacing decision is one to revisit by looking
at renders rather than by imagining them.

The logo's rendered size is still read from the PNG header rather than
copied into the renderer, which is what made this reversal a one-line
change with nothing to keep in sync.
