Installs Oswald (OFL-1.1, from googlefonts/OswaldFont) under
~/.fonts/o/Oswald with its license, and points the clock numerals at it
for the squared look the rounded Noto Sans Black did not have.
Per-widget fonts needed no new machinery: card.font() already takes any
family string, so FONT_* are shared defaults rather than a restriction.
FONT_CLOCK joins them, and the weather card keeps FONT_HEAVY, so the two
no longer have to agree.
Cairo still cannot ask for a weight above bold, so a heavier cut is
selected by family name as FONT_HEAVY already did. Worth knowing that
fontconfig substitutes a default for a family it does not recognise,
which is indistinguishable from the font not applying; fc-match tells
you which happened.

The date rendered as "16 /SEP /2026", each slash jammed against the
next glyph. measure() returns the ink width, which ignores leading and
trailing spaces because a space carries no ink, and clock.lua was using
it to advance a cursor. Measured: " / " covers 6px of ink but advances
14px, so every separator lost 8px.
Splits the two uses that were conflated in one function. measure() is
for centring and right-aligning, where ink width is what you want;
advance() returns x_advance and is for laying out runs of text left to
right. The clock's date now uses advance() and reads "16 / SEP / 2026"
with even gaps, verified by screenshot.
Worth the split rather than changing measure() in place: text_right is
a correct caller of the ink width, so one function cannot serve both
and silently returning the advance would have broken alignment
instead.

Two defects, both found by review of the Cairo work and both confirmed
by experiment rather than reasoning.
The palette mechanism could not have worked. conky_parse('${color3}')
returns an empty string: conky's colour variables emit renderer escape
codes into conky.text, they never evaluate to a hex string, and
${default_shade_color} is not a variable at all, so conky_parse hands
the literal text back. conky.config is not exposed to Lua either
(_G.conky is nil) and conky_info carries only cpu_count and
update_interval. What Lua does get is conky_config, the config file's
path, so the colours are now parsed out of that file, where UDT has
already substituted real hex. The pattern needs [%w_]+ rather than %w+
or it misses default_color and default_shade_color.
The card fill also duplicated the border colour, both being color3, so
filling at 0.55 alpha and stroking the hairline at 0.9 in one hue made
the border invisible and the cards read as blobs rather than the
mockup's thin outlines. The fill is default_shade_color now, a role
every scheme already defines.
card.measure allocated a cairo_text_extents_t per call, which leaks:
5000 allocations grow Lua's heap by 182KB that GC never reclaims, and
:destroy() on each does not help, measured at the same 182KB. One
reused module-level struct costs 0KB. A draw hook running every 2s
would have bled memory for as long as conky stayed up, which no
screenshot would ever reveal.

Rounded-rect card with a hairline border, text helpers with measured
alignment, and font selection.
Cairo's font API stops at BOLD, so the Black face is reached by family
name instead of weight: at size 90, '13' measures 100px as Noto Sans
Black against 94px as Bold, confirming the heavier face is selected.
The card radius is clamped to half the shorter side, because a larger
radius makes the corner arcs overlap into a bowtie.
