The plugin theme drifted from the website palette over time: cyan
sat at #00B8D4 instead of the brand #00BED2, the warm highlights
were industrial amber rather than Ember Orange, and active tabs and
title bars were rendered in slate violet — a shade not part of the
brand at all.
This commit moves every HellionStyle slot onto the Arctic Cyan +
Ember Glow tokens documented in the website's BRANDING.md:
- Primary cyan slots (Button, CheckMark, Slider, Separator) now
use brand-color / brand-color-light / brand-color-dark
- Window title bars and the active tab use brand-color-dark as
Identity teal — slightly varied so it reads as identity rather
than as another action surface
- Unfocused-active tabs drop to a deeper teal so the unfocused
window's tab is still visible without pulling focus
- Resize grips and scrollbar grabs lift into Ember Orange on hover
and active states, replacing industrial amber
- Window, child, popup, frame and header surfaces follow the
brand background ladder (#070B12, #0C1220, #141E30, #1A2538,
#22303F)
- Borders use the brand cyan at 40% alpha (matches --border-brand
on the website) instead of neutral steel grey
The slate violet tertiary palette is gone. Brand tokens are
declared once and the slot constants alias them, so a future brand
shift only needs to touch the Identity / Accent / Primary stages.
