/* Both of these used a solid "chip" background behind the text at one

   it read as a crude rectangular text box (Paint-style), not part of
   the design. Replaced with a heavy multi-direction text-outline
   instead: four small tight shadows (one per side) form a solid dark
   edge hugging each glyph, plus two soft wider glows for depth -- no
   background shape at all, just outlined white letters. This is a
   real trade-off, not a free win: unlike the chip, an outline this
   strong is NOT counted toward WCAG 1.4.3's 4.5:1 contrast ratio by
   the spec (or by axe-core) no matter how solid it looks, so this
   knowingly reintroduces the contrast gap the chip closed (sampling
   found ~1.2:1 against the photo's brightest patches). Kept because
   the user explicitly chose this trade-off after that was explained. */
