secondary used text-fg-2 (--mf-text-2), which in dark mode is a fairly
dim mid-gray (#8a8a8e) that read poorly against the dark bg-btn fill,
even though the same class looks great in light mode where --mf-text-2
is a dark, high-contrast gray. Use text-fg instead, which is tuned
bright in dark mode and dark in light mode, so both modes get good
contrast from the same class. Drop the now-redundant hover:text-fg
since resting state already uses it.
Button's accent variant used bg-accent-btn (15% alpha) while the
active-track highlight in ListRow/TrackList uses bg-accent-tint (8%
alpha) with the same text-accent-soft title color, so a button like
"Reproducir" sat at a visibly different tint than the row it plays.
Use bg-accent-tint for accent's resting background too, so both read
as the same accent color; hover still steps up to bg-accent-btn-hover.
Button used Tailwind's bare `transition` utility, whose default
property list includes background-color. Since the button's bg is a
CSS custom property recomputed every frame by the same 600ms hue
animation the main background uses, that extra transition smoothed it
on a different (~150ms) timing, so its color change didn't match the
page background's.
Add a btn-transition utility that mirrors Tailwind's default
transition list minus background-color, so the button's background
tracks the hue animation frame-for-frame like the rest of the app,
while hover/focus feedback (text color, ring, filter) still transitions
normally.
backdrop-blur samples whatever is actually behind the element, so two
secondary buttons with identical classes could render differently
depending on nearby content (e.g. dark album art bleeding into the
blur near the spotlight card). Replace it with a fixed color-mix that
reproduces the same result mathematically instead of sampling pixels:
45% --mf-elevated over the hero/spotlight surface's own tint color
(16% --mf-hero-tint over --mf-bg, the same ratio hero-surface itself
uses), computed via CSS color-mix() rather than a backdrop-filter.
Verified against the previous blur version: both now compute to the
identical color(srgb 0.9329 0.9611 0.9332), matching what the blurred
button rendered against the same hero background, but fixed so every
secondary button is now guaranteed pixel-identical regardless of what
happens to be nearby.
Sampling whatever's behind the button via backdrop-filter meant two
secondary buttons could render differently depending on what happened
to be nearby (e.g. dark album art bleeding into the blur), so
"Explorar musica" and "Aleatorio" ended up visibly different colors
despite being the same variant. Replace it with a fixed, hue-tied
translucent tint (bg-accent-tint, the same token family accent already
uses) so every secondary button computes to the identical color, ties
into the same dynamic accent hue as the rest of the app, and reads as
a softer sibling of the accent button instead of an unrelated gray.
Hover now steps up to bg-accent-btn (same hue family, stronger) instead
of a flat, hue-agnostic gray. Removed the now-unused --mf-btn-bg-hover/
--color-btn-hover tokens.
bg-elevated is fully opaque and only hue-matches --mf-bg (the plain
page background), so it stayed stark white on the hero/spotlight cards,
which use a separately-computed, more saturated gradient (--mf-hero-bg/
--mf-spotlight-bg). An opaque fill can never pick up that color no
matter what hue it's tied to.
Make it translucent (bg-elevated/45) with backdrop-blur-lg so it
samples and lightly tints whatever is actually behind it, hero card,
spotlight card, or plain background, instead of only matching one of
them.
secondary was fully bg-transparent (invisible at rest) or a flat neutral
overlay (clashed next to accent-tinted buttons and looked different
depending on what surface it sat on). Use bg-elevated instead, which is
already derived from the same hue as --mf-bg, so the button is always a
faint, minimal step above whatever page background it's on, and shifts
with it automatically.
Drop the now-unused --color-btn/--mf-btn-bg tokens.
secondary used a flat, static tint that only worked over a plain
surface, so it looked out of place on the hero's hue-shifting gradient.
Add a backdrop blur (no border, per feedback) so it always reads
against whatever's actually behind it. Gave the button its own
background tokens instead of aliasing --mf-surface-2, and dropped the
now-unused --color-btn-glass tokens left over from the removed glass
variant.
The secondary/glass Button variant used a flat, fairly opaque black or
white tint with no blur, so it didn't read as glass and clashed with
the hue-shifting hero background. Add a backdrop blur and a hairline
border (matching the app's existing glass-bar/glass-panel treatment)
and lower the tint opacity.
Wire up the already-computed but unused --mf-accent-muted token as
--color-accent-muted, and use it for the accent Button variant's text
instead of the higher-chroma --color-accent-soft, so it reads softer.
