The earlier 'use next/script beforeInteractive' attempt still emitted a
<script> tag inside React's renderer and therefore still tripped React
19's 'Encountered a script tag' warning on every page that used the root
layout, which is one of the documented triggers of the
chunk.reason.enqueueModel flight-client crash in
vercel/next.js#92362.
ThemeScript now returns null. The first paint picks the OS preference via
a @media (prefers-color-scheme: dark) block in globals.css so no flash
occurs for users on the default. An explicit stored choice is applied
synchronously by ThemeSync (a small client component) on mount — a
trade-off the shadcn dark-mode guide accepts too.
Also fixes the .light class selector the new media-query rule introduces.
Palette:
#051a2d Deep Navy -> page (dark base) + text-primary (light)
#068187 Teal Green -> brand (light mode, AA contrast on white)
#10bbc3 Aqua Blue -> brand (dark mode, vibrant on navy)
#fea24f Sunset Orange -> priority-high
#a60e35 Crimson Red -> accent + priority-critical
The plan's reservation rules are preserved: the crimson accent still appears
only on overdue dates, the inbox count badge, and critical priority.
