   NAMESPACING: every rule is scoped to the `.lkyspp-ai` wrapper and
   every class is prefixed `lky-`, so this stylesheet can be enqueued
   inside an existing WordPress theme without restyling the theme or
   being restyled by it (e.g. Bootstrap `.btn`, underscores
   `.site-header`). No bare element selectors leak outside the wrapper.

   Brand colours (LKYSPP Brand Toolkit §2.6):
   - Corporate Maroon  #782F40  (Pantone 195)
   - Corporate Grey    #898D8D  (Pantone 423)
   - Secondary Orange  #E57200  (Pantone 152)

   The ring colour is driven by an inherited custom property rather than by an

   specificity to `.lkyspp-ai a:focus-visible` (0,2,0 vs 0,2,1) and silently do
   nothing; redefining the property instead inherits cleanly into every
   descendant, so dark sections always get a white ring. */
