LWTitle-title.woff2 — how it was made, and WHY IT IS NOT CALLED SPINWERAD (2026-09-05)

SOURCE   Spinwerad 0.3 by gluk (gluksza@wp.pl) — spinwerad.ttf, 695 184 bytes.
         SIL Open Font License 1.1 — the licence text is Spinwerad-OFL.txt, which is the
         author's own file and keeps the author's own name.
         Recoverable from this repo's history:  git show <pre-subset-rev>:lab/fonts/Spinwerad.ttf
SUBSET   10 132 bytes, printable ASCII (U+0020–007E) — 68x smaller than the 695 KB original.

THE NAME.  A subset is a "Modified Version" in the OFL's own words ("any derivative made by adding
to, deleting, or substituting ... or by changing formats"), and this file is both subset and
converted TTF -> WOFF2.  "spinwerad" is a Reserved Font Name, declared twice: in Spinwerad-OFL.txt:2
and in the original binary's own nameID 13.  OFL section 3 forbids a Modified Version from using a
Reserved Font Name as "the primary font name as presented to the users", and the TERMINATION clause
makes the whole licence null and void where a condition is not met — so shipping a subset
under the name "Spinwerad" would void the grant that lets us ship the file at all.
The derivative is therefore called LW Title: nameID 1 = "LW Title", 4 = "LW Title Bold",
6 = "LWTitle-Bold", and the CSS family in skin.css is 'LW Title'.  UN-SUBSETTING DOES NOT FIX THIS
(a WOFF2 conversion is still a Modified Version, and it costs 695 KB); renaming does.
The binary KEEPS gluk's nameID 0 and 13/14 verbatim, and carries a nameID 10 that says what it
derives from — OFL section 4 expressly permits acknowledging the author, and the acknowledgement
should exist.

COMMAND  python -m fontTools.subset Spinwerad.ttf \
             --unicodes="U+0020-007E" --flavor=woff2 --output-file=LWTitle-title.woff2 \
             --layout-features='*' --no-hinting --name-IDs='*'
         then rewrite nameIDs 1, 3, 4 and 6 so that NO user-facing name contains "spinwerad",
         add nameID 10 (the derivation),
         keep 0, 13 and 14, and drop the Macintosh (platform 1) name records.

GLYPH SET   Printable ASCII (U+0020–007E) — #title .word, .nb-logo .word ("WAVES"), and
            the notebook title .nb-title ("NOTEBOOK" and custom titles).

FONTLOG (gluk's, carried forward from the original release; the OFL FAQ's recommended place for a
modifier to record what changed)
  15.01.2009  gluk (gluksza@wp.pl)   spinwerad Version 0.2 — first release
  07.02.2009  gluk (gluksza@wp.pl)   spinwerad Version 0.3 — spinweradC.ttf
  2026-09-05  λWAVES — subset to the five letters of "WAVES", converted to WOFF2, and RENAMED to
              "LW Title" per OFL section 3.  695 184 -> 3 176 bytes.  spinweradC.ttf was referenced
              nowhere and is not shipped.  Neither gluk nor the Spinwerad project produced or
              endorses this derivative.
  2026-09-08  λWAVES — subset expanded from 5 glyphs to printable ASCII (U+0020–007E, 10 132 bytes)
              so that .nb-title ("NOTEBOOK" and custom user titles) renders uniformly in LW Title
              rather than falling back piecemeal to Roboto.
