/* Text entry fields should not draw focus borders/rings. The caret and local
   field fill communicate editing state; buttons and other controls keep their
   focus-visible treatment.

   OPT-OUT: `data-focus-ring`.

   The reasoning above assumes a FILLED field: the fill and border change on
   focus, so the ring would be a third signal. A bare field (an inline value
   cell drawn as a single underline, no background) has no fill to change, so
   the same rule leaves it with a measured focus contrast of 1.05:1 against
   the page in the light theme, i.e. no visible focus at all. Those fields
   carry `data-focus-ring` and get the standard green ring below.

   The exception lives in the rule it excepts, not in the page CSS: this
   selector is specificity 0,8,1 with !important, which no reasonable
   page-level selector can outrank. A page that tries loses silently, and the
   only symptom is an invisible focus ring. Found 24.8.2026 on the execution
   surface's inline reading field. */

   iOS:n zoom fokusoidessa — yksi sääntö, ei kenttä kerrallaan

   Safari zoomaa sivun kun kosketuslaitteella fokusoidaan syötekenttä jonka
   kirjasin on alle 16 px. Zoom ei palaudu itsestään: käyttäjä jää
   suurennettuun näkymään ja joutuu nipistämään takaisin. Se on yksi
   häiritsevimmistä mobiiliverkon kokemuksista, ja se syntyy yhdestä
   pikselistä.

   Mitattu 29.8.2026 (390 × 844, kosketus): yhdeksän kenttää neljällä
   pinnalla oli 14,5 px — Asetusten seitsemän, Työtilan kirjoitin ja Kodin
   kysymyskenttä. `mobile.css`:n oma 16 px -sääntö oli olemassa mutta se
   koski vain `.form-*`-luokkia eikä pärjännyt sivukohtaiselle
   spesifisyydelle.

   Siksi sääntö on ELEMENTTITASOLLA eikä luokissa: jokainen tekstinsyöttö
   on katettu riippumatta siitä mikä luokka sillä on ja kuka sen tyylittää.
   `max(16px, 1em)` ei kutista mitään — se vain estää alarajan alituksen ja
   säilyttää isommat koot sellaisenaan.

   Osoitinakselilla eikä leveydellä: sama zoom tapahtuu iPadilla, jossa
   leveysraja ei olisi lauennut lainkaan.

   Valintaruudut ja radiot rajattu ulos: ne eivät ota tekstiä vastaan eikä
   Safari zoomaa niihin, mutta niiden koko on visuaalinen ja kasvaisi. */

           Elementtitason sääntö (0,0,1) häviää jokaiselle luokalle (0,1,0),
           ja kentillä ON luokat: `.form-select` ja `.compositor__input`
           jäivät 14,5 px:ään vielä sen jälkeen kun sääntö oli olemassa.
           Vaihtoehto olisi luetella kaikki luokat, ja se on juuri se muoto
           joka epäonnistui jo kerran (`mobile.css`:n oma 16 px koski vain
           `.form-*`-luokkia).

           Tämä ei ole tyylittelyä vaan ALUSTAKÄYTTÄYTYMISEN suoja, samaa
           luokkaa kuin `prefers-reduced-motion`: se estää selainta tekemästä
           jotain jota käyttäjä ei pyytänyt eikä voi perua.

           Todennettu ettei mikään kenttä KUTISTU: kaikki kentät mitattiin
           ennen ja jälkeen kahdella leveydellä, ja jokainen arvo joko
           kasvoi tai pysyi samana. */
