Yourz fef2cab31e fix(website): prevent video glitch when c-projection.webp loads on /customers (#12060)
*PR Created by the Glary-Bot Agent*

---

## Summary

Fix the video position glitch on `/customers` caused by
`c-projection.webp` loading.

## Root cause

In `HeroSection.vue` the hero `<img>` for `c-projection.webp` had no
`width`/`height` attributes, so the browser reserved no space for it.
When the image finished loading, the layout shifted ~192px, pushing the
`VideoPlayer` below it. `useHeroAnimation` registers a GSAP
`ScrollTrigger` parallax against the video in `onMounted` (before the
image is loaded), so the cached scroll geometry then went stale and the
video visibly glitched.

## Fix

- Add explicit `width="1568"` / `height="1763"` to the `<img>` (the
image's native size) so the browser reserves the correct aspect-ratio'd
space upfront.
- Add `h-auto` so the height attribute doesn't override the responsive
layout.
- Refresh `ScrollTrigger` on the image's `@load` (with `refresh(true)`
so measurements happen after layout has settled) as a defensive measure
for any sub-pixel adjustments.

## Test coverage

Added `apps/website/e2e/customers.spec.ts` with a regression guard that:
1. Asserts the hero `<img>` declares numeric `width`/`height`
attributes.
2. Asserts the unloaded image still reserves vertical space (>100px),
which is the exact property that prevents the video from jumping when
the image finishes loading.

Verified the test fails when the `width`/`height` attributes are removed
and passes with the fix applied.

## Verification

- `pnpm typecheck` clean.
- `pnpm test:unit` (website app) — 30/30 pass.
- `pnpm test:e2e customers.spec.ts --project=desktop` — passes.
- ESLint + oxfmt clean on changed files.
- Manual Playwright verification confirmed the video bounding rect stays
at `top=785, height=628` through the full image load lifecycle.
Reverting the fix in DevTools and re-loading the image reproduces the
original ~192px shift.

## Out of scope

`apps/website/src/components/contact/FormSection.vue` uses the same
`c-projection.webp` pattern (also without `width`/`height`). It runs
`useHeroAnimation` with `parallax: false`, so the symptom is much
smaller — leaving as a follow-up to keep this PR minimal.
