Function
The type scale steps down below sm. ENGLISH·COURSE contains no spaces,
so it cannot wrap: at the full 17px/0.28em it measures 223px and leaves
too little of a 320px viewport for the header's locale and theme controls.
At 13px/0.18em it measures 153px, ending 169px into a 320px viewport and
leaving the remaining 151px to the locale and theme chips — measured in
Chromium in all three locales, which render it identically because the mark
is locale-invariant.
The Immersion Cinema wordmark:
ENGLISH·COURSE, letter-spaced, with the middle dot in the gold accent. Links wherever the caller points it (locale-aware), defaulting to the locale home — the header sends a signed-in learner to My learning instead. The visible text carries the accessible name, so no extraaria-labelis needed.The mark is not localized. It names the product the site publishes to the outside world, so it reads the same in every locale and matches what the metadata announces as
og:site_name.
