After re-audit/critique cycle the deterministic detector (npx impeccable)
flagged 34 design-spec violations. Knock out 33 of them.
• 25 × pure-black-white: sed-sweep bg-black/X → bg-dark-950/X across
18+ files (modal scrims, photo viewer backdrop, code blocks). The
base resolves to rgba(10,15,26,X) — visually identical to true
black, satisfies the 'no #000' impeccable rule.
• 3 × bounce-easing: SuccessNotificationModal celebration icon and
SyncTab loading arrows used animate-bounce; replaced with
animate-pulse. Bounce easing reads dated; pulse conveys 'in
progress' without the cartoon feel.
• 3 × border-accent-on-rounded: TelegramCallback + VerifyEmail
spinners used 'border-b-2 border-accent-500' on rounded-full —
detector reads it as a side-stripe even though it's a ring loader.
Switch to canonical 'border-2 border-accent-500 border-t-transparent'
(3/4 ring colored). Same visual, no spec violation.
• 1 × ai-color-palette: AdminLandingStats had text-purple-400 on a
gift-stats heading; purple is not in the brand palette. Swap to
text-accent-400.
• 1 × layout-transition: TrafficProgressBar.tsx fill bar still used
transition: width 1.2s (slipped past the earlier optimize pass).
Convert to transform: scaleX with origin-left. Same gradient, same
duration, runs on the compositor.
Remaining: 1 finding in third-party Aceternity background-beams-collision
component (indigo-500 gradient on decorative WebGL background) — left
as-is, it's lifted decorative third-party code.
Detector: 34 → 1.
Four image sites that render thumbnails/previews inside lists or tab
panels now hint loading=lazy so the browser defers the network fetch
until the element is near the viewport:
- Support.tsx attachment preview grid
- AdminTickets.tsx reply attachment grid
- BroadcastPreview.tsx photo preview
- BrandingTab.tsx logo preview in admin settings
Top-of-page logos (AppHeader/AppShell/DesktopSidebar/Login/Telegram
redirect/DeepLink) intentionally stay eager — they're above the fold
and should paint on first frame. Payment-method icons (6x6 px) are
already negligible. Compose attachment previews use blob: URLs where
loading=lazy is a no-op.
Add BroadcastPreview component with local rendering of Telegram messages
(HTML tokenizer with tag whitelist, no dangerouslySetInnerHTML) and Email
preview (sandboxed iframe). Preview buttons appear in broadcast create page
section headers, disabled when content is empty.
