   2026-08-15 — OPTICAL PRODUCT DETAIL / RETICLE CIRCLE LOCK

   Scope:
   - Shared by every optical product detail page using the Section 01 hero.
   - Keeps the reticle presentation perfectly circular at every viewport size.

   Why:
   - The previous rule used width + aspect-ratio while inheriting max-height
     constraints from the generic hero image rule. On some narrow / short
     viewports the browser could clamp only one axis, visually stretching the
     reticle into an ellipse.
   - This rule assigns an explicit equal width and height per breakpoint, so the
     presentation cannot become elliptical.
