/* The lock-up is ONE unit, and the wordmark sizes it. Every part below is em of .brand's font-size,
   at the ratios measured off the approved OTTO-182 artwork (Otto 52u → mark ink 43.55u = .8375em,
   CARE 30u = .577em, gaps 12.8u/11.5u ≈ .235em). Change font-size and the whole lock-up scales.

   Why it moved (OTTO-186): OTTO-183 shipped the mark at 1.35em against a 1.18rem wordmark — the mark
   got fitted to the type that was already there, and that type was sized back when the brand was a
   gold dot and the word "Otto". The mark needs ~25px to read; at .8375em of 1.18rem it was a 16px
   speck, so it was pushed to 1.35em to clear the floor. That bought legibility by breaking the drawn
   ratio: mic 1.6x oversized, wordmark rendering 35% smaller than the approval art. The fix is the
   other direction — size the type to the lock-up (1.8rem ≈ the artwork's own nav specimen), and the
   mark reaches 24px at its correct .8375em.

   height: the viewBox is cropped to the mark's ink, so height IS visible mic height, and
   `align-items: baseline` drops the mic's base onto the type baseline for free (a replaced element
   baselines on its bottom edge). Do not pad the viewBox or the mic starts floating. */

  /* OTTO-183: `.brand small { display: none }` used to live here, hiding "care" below 820px — on
     every phone AND tablet. The period is the dot in the domain (otto.care), not a full stop, so
     hiding the word left a gold dot pointing at nothing: the logo read "Otto." on the surface most
     visitors see. OTTO-182 made "care" load-bearing, so it stays at every width.
     OTTO-186: the `.brand { font-size: 1.05rem }` shrink that replaced it is gone too. It existed to
     buy nav width, and once the anchors collapse (below) the width is there — so the lock-up is now
     ONE size at every viewport. That is also the only way the mark stays legible on a phone: shrink
     the lock-up and the mic goes with it, since the parts are em. Don't re-add a brand font-size or
     a px gap here — either one skews the drawn ratios at exactly the width most visitors see. */
}

/* OTTO-186 — the marketing nav's in-page anchors step aside, leaving brand + CTA on one line.
   Why they go: the mark needs ~25px of ink to read as a microphone rather than a speck, and at its
   drawn .8375em ratio that demands a ~30px wordmark — a ~150px lock-up. The nav cannot afford that
   beside four links on a phone. It could not afford them BEFORE the mark existed either: at 375px
   they already stacked three deep into a 146px sticky bar eating a fifth of the screen. Hiding them
   costs little — this is one scrolling page, every section is a thumb-flick away, and the CTA is the
   only nav item doing conversion work.
   660px, not the 820px sibling above: MEASURED, the four links still sit on one line down to 642px,
   so collapsing at 820 would strip navigation off tablets that have the room for it.
   Scoped to href^="#" deliberately: it must NOT touch /investors/, whose nav is real page-to-page
   navigation. Hiding those would strand a reader with no route to the other three documents.
   The row's flex-wrap is a safety net for ~320px, where brand + CTA genuinely cannot share a line
   and should stack rather than overflow the page. */
@media (max-width: 660px) {
  .nav nav a[href^="#"]:not(.nav-cta) { display: none; }
  .nav .row { flex-wrap: wrap; row-gap: 4px; }
}

/* OTTO-186 — /investors/ can't collapse its links (see above), so once the full-size lock-up
   crowds them they become a deliberate right-aligned column beside the logo — a menu, which is what
   they are — instead of wrapping into an accidental-looking three-deep stack.
   Contact leaves the column rather than becoming a fourth row or an icon. It is a mailto, and the
   same address already sits in the footer of every investors page ("Michael Rennick · mikerennick@
   …"), so it is redundant here, not lost. An icon does NOT help: in a COLUMN it still costs a full
   row (measured: 167px with the icon vs 131px without) — shrinking an item only buys anything when
   items share a line. Contact keeps its nav slot above 580px, where there is room for it.
   600px, its own breakpoint and NOT the 660px sibling above: MEASURED, these four links and the
   lock-up share one line down to 585px and break at 584px, so stacking at 660 would column-ise a nav
   that still fits fine. 600 rather than a tight 584 is deliberate margin — the threshold is a
   function of the links' RENDERED width, which moves with font availability and platform metrics, and
   undershooting it re-opens a band where the row wraps two-deep instead of columning (a 580 value did
   exactly that at 581-584). Prefer columning a few px early over a wrapped band.
   Re-measure both thresholds if the link labels change — and measure AFTER document.fonts.ready:
   probing at navigation-commit reports ~573 here, 11px off, because the webfont has not applied yet.
   Inert on the marketing page: only the CTA is visible by this width, and a column of one renders
   exactly like a row of one. */
