poprhythm 531d1aa0aa Split show and DJ name onto separate rows at 2x 
Show names can run up to ~60 characters -- nowhere close to fitting
even at 2x's doubled width, so that line stays a Marquee regardless.
DJ/host names are assumed short enough to just fit without scrolling,
so that line is centered static text instead, using the same
codepoints()-based length check and Marquee fallback already
established for time_temp (a bare len() would overcount any multi-byte
character in the name).

2x only, per explicit scope check -- splitting into two rows needs a
spare vertical row that doesn't exist at 1x's tighter layout; 1x keeps
the existing single combined show+host Marquee line unchanged.

An empty-host placeholder box keeps the row position fixed when no DJ
is credited, matching the existing "always render both rows, even
empty" rationale for show/host already noted above. Verified against
live data (activeShow currently null): empty show line, host line
("Marlowe") correctly centered on its own row, no vertical overflow.

# column instead of relying on a 1px coincidence. Always Marquee at
# 1x, where the available width is tighter regardless of length.

# least one multi-byte character (the \xb7 separator, \xb0 in the temp,
# if any) -- confirmed len() reports 16 for a real 14-character

# Album art gets a slow "Ken Burns" breathing effect: starts and ends on
# the full frame, easing in to a zoomed-in crop at the midpoint, on a
# continuous loop -- not a one-shot reveal. A one-shot version (start
# zoomed in, end on the full frame, then hold) looked jumpy: since the app
# re-renders on NOWPLAYING_TTL
# and each fresh render restarts its own animation from tick 0, whatever the
# *previous* pushed image happened to be showing at that moment gets
# abruptly replaced by a fresh zoomed-in frame. The back-and-forth loop
# doesn't eliminate that (a server-side re-render always restarts at tick 0
# regardless), but ending exactly where it started means the animation also
# loops seamlessly on-device between refreshes.
#
# Duration is intentionally short (a handful of seconds each way), not the
# ~60s round-trip originally tried: on the real device/server, a fresh
# render replaces the still-playing animation well before a minute-long
# cycle can complete, so only the outbound half (zoom out) was ever visible
# and it never appeared to "zoom back in". A short loop guarantees at least
# one full out-and-back cycle plays before that happens.
#
# Art is rendered slightly oversized (36x36, vs. the 32x32 display slot).
# animation.Scale is only ever applied at 1.0 or above here -- empirically,
# scaling this *below* 1.0 (tried while chasing a "show the literal whole
# image at rest" design) reintroduces a real, on-device black-border bug:
# below roughly 0.9-0.95 a visible gap opens up along one edge, well before
# the math (scaled size vs. box size) would predict any gap at all, so it
# isn't a simple "runs out of image" overflow -- treat scale < 1.0 as
# unsafe regardless of the numbers. That rules out "native size at rest,
# shrink down to reveal everything" -- so instead ART_SIZE is kept just
# barely larger than ART_SLOT: at the safe floor of scale = 1.0, only
# ART_SLOT/ART_SIZE (~89%) of the image is visible, which reads as
# "fully zoomed out" (a sliver cropped off each edge, not noticeable) while
# leaving just enough headroom above 1.0 for a real zoom-in effect. The
# zoom-in amount itself (`zoom_scale`, from the ZOOM_LEVELS schema option)
# must stay >= 1.0 for the same reason.

# i.e. no visible movement). Wrapping the art in a Transformation shifts
# its crop by a few pixels versus a bare, unwrapped Image in the same
# Box -- confirmed empirically, even at an explicit Scale(1.0, 1.0) --
# so a plain-Image "off" path and a Transformation-wrapped zoom path
# don't actually agree on framing despite both nominally being "scale
# 1.0". Using the same wrapper unconditionally guarantees the "off"
# state and the rest state of every zoom level line up exactly.
#
# `origin` picks where the zoom centers on, which also gives a free
# "zoom to a different spot each time" effect (ZOOM_SPOTS above) by
# just varying it per track. An earlier version tried to recenter the
# zoom by pairing Scale with a *computed, animated* Translate, on the
# mistaken assumption that Scale's default pivot is the top-left
# corner -- it isn't; pixlet's own docs say the default origin is
# already the center (0.5, 0.5). That Translate was sized assuming
# Scale had no self-centering at all, so it overcorrected, visibly
# skewing the zoom toward the bottom-right -- the opposite of the bug
# it was meant to fix. Since `origin` already does directly and
# correctly what that Translate was clumsily approximating, this uses
# `origin` for the zoom-position pivot.
#
# Separately, though: `origin` only has any effect while Scale is
# actually changing frame to frame -- confirmed empirically (varying
# origin_x/origin_y produced byte-identical output for a Scale that's
# pinned to the same constant value across every keyframe, at *any*
# scale, not just 1.0). At the two instants where this animation's own
# Scale is momentarily constant (percentage 0.0 and 1.0, i.e. "rest"),
# there's nothing for origin to pivot, so the crop that's left falls
# back to render.Box's own default handling of an oversized
# Transformation child -- which isn't a centered crop at all: checked
# with the calibration tool (concentric rings plus a center crosshair),
# the crosshair sat several pixels down-and-right of where a centered
# crop would put it, i.e. the box was effectively showing more of the
# image's top-left and cropping away a disproportionate amount from
# the bottom-right -- matching exactly what was reported ("losing
# ~10% on bottom and right, not zoomed").
#
# Fixed with a *constant* Translate -- the same (tx, ty) at every
# keyframe, found empirically via the calibration tool's crosshair
# (the value that put it dead-center at rest also held up at peak
# zoom). This is not the same mistake as the earlier abandoned
# attempt: that Translate *varied* over the animation (fighting
# Origin's own pivot, and per pixlet's own source, interacting badly
# with Scale's continuous interpolation vs. Translate's per-frame
# rounding -- the "periodic pop" bug). A constant value changes
# nothing frame to frame, so there's no interpolation for it to
# mismatch against -- confirmed smooth across a full cycle, no pop.
# It's purely compensating for render.Box's own fixed crop bias, which
# doesn't depend on zoom_scale/zoom_position at all.

# duplicate, differently-tinted copies of the art, each cropped to a
# shifting horizontal band -- plus scanlines and viewfinder-style corner
# tick marks. Built here from scratch against the *live* art via
# filter.Hue, not a bundled asset -- pixlet's `filter` module (confirmed
# real and working, same as `animation.Origin`) can recolor an arbitrary
# widget, including an already-zoomed render.Image, so the glitch bands
# reflect whatever's actually on screen rather than a generic texture.
# This replaced an earlier version built as a bundled static.gif overlay
# (first sparse noise specks, briefly a VHS-footage-derived band) -- that
# approach is still viable for projects without filter.star, but once a

# motion) rather than a reproduction of unseen code. Band proportions

# enough to push a real render past the 460KB device limit if sized
# against the full window (measured 481KB at the time). Those bands are
# gone now -- this only drives the base-art jitter, built on
# render.Sequence + _glitch_shift (Padding), which compresses far

# window at rest. That didn't work how a positive Padding (which
# reliably *grows* a widget's declared size -- used elsewhere in this
# file, e.g. _glitch_band) does; empirically it went blank partway
# through instead of revealing new rows at the top, which is what
# "scanlines disappearing at the bottom without regenerating at the
# top" looked like.
#
# This avoids all of that: the buffer is only ONE extra
# SCANLINE_SPACING taller than the art slot (the same small, proven-
# safe oversized margin used everywhere else in this file -- e.g. the
# zoom's own ART_SIZE vs. ART_SLOT), and instead of one big sweep it's
# a repeating sawtooth -- ramp down by exactly one SCANLINE_SPACING,
# then snap back to 0 and repeat. Since the pattern repeats every
# SCANLINE_SPACING (see SCANLINE_COUNT above for why), a one-period
# displacement looks identical to the starting position, so the snap
# is invisible -- a standard infinite-scrolling-texture trick -- while
# the translate distance never has to leave the small range already
# confirmed safe.
#
# SCANLINE_SPACING is computed from the *scaled* art_slot (not a

# resolution -- SCANLINE_COUNT=4 still divides it evenly (32/4=8 at
# 1x, 64/4=16 at 2x), which is what the sweep's seamless loop depends
# on (see the note above SCANLINE_COUNT for why that divisibility
