Subject: [PATCH] At 2x, show time/temp as static text instead of scrolling it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First experiment in using 2x's extra width for something other than
just stretching the 1x layout: the time/temp line usually fits without
scrolling once the text column doubles in width. Marquee is unneeded
overhead for short, non-truncated text.

Guarded by a length check (<=15 chars), not just scale==2: pixlet has
no way to measure rendered text width from within Starlark, and
tom-thumb is variable-width, so this is a heuristic rather than an
exact fit check. Measured via the CLI: a realistic worst case like
"12:59 pm · 100°F" (16 chars -- 2-digit hour, 3-digit temp) renders at
63px against a 64px budget, just 1px of margin -- too close to rely on.
15 chars keeps a real margin (59px measured) against overflowing into
the art column. Falls back to Marquee past that length, and always at
1x regardless of length (tighter width there either way).
