    "summary": "Every logo needs a minimum buffer of empty space around it. Violating clear space reduces recognition and damages brand authority. Define it; enforce it.",
    "description": "Clear space — sometimes called exclusion zone or safe area — is the minimum amount of empty space surrounding the logo that no other element may enter. Most brand guidelines define it in terms of an element of the mark itself (e.g., 'the height of the uppercase letter in the wordmark on all sides'). Clear space lets the logo breathe and keeps it visually dominant in any context. Violating it — placing text right against the mark, overlapping with imagery, crowding into a corner — signals amateurism and weakens recognition. Define clear space as part of the brand system and enforce it in design reviews and templates.",
    "implications": [
      "Derive clear space from a unit of the mark itself so it scales: 'clear space = height of the uppercase letter' or 'clear space = width of the primary glyph'.",
      "Apply clear space to all four sides, including when the logo sits against an edge or another element.",
      "In responsive layouts, clear space often needs to scale — don't hard-code it in pixels.",
      "In component libraries, bake clear space into the logo component so developers can't violate it accidentally.",

    "summary": "Below a threshold, logo detail degrades and recognition collapses. Define minimum sizes per context — screen, print, favicon — and use appropriate simplified marks when space is tight.",
    "description": "Logos are designed to be recognizable at a particular range of sizes. Below the minimum, details blur, letter spacing breaks down, and the mark loses its intended form. Most brand systems define multiple minimum sizes for different contexts: desktop header, mobile header, print, favicon, app icon. Often this requires alternate marks: a full wordmark-plus-symbol for large contexts, a symbol-only version for constrained ones. The best systems produce these variants in the same design pass so the brand remains coherent across scales.",
    "implications": [
      "Define minimum sizes explicitly in the brand guide: e.g., 'full wordmark ≥ 120px wide; symbol-only below that.'",

      "Test logos at favicon size (16x16, 32x32) as part of design review — many otherwise-beautiful marks fall apart here.",

The list is remarkably consistent across well-designed systems: don't stretch; don't skew; don't drop-shadow; don't gradient-overlay; don't outline; don't bevel; don't rotate; don't recolor outside the approved palette; don't reverse the lockup; don't combine with other marks.

    "description": "New brands often sprinkle the logo everywhere: in the hero, in every card, in the footer, watermarked across hero imagery. The instinct is 'reinforce the brand.' The effect is the opposite — when the logo is everywhere, it stops being noticed, the layout feels cluttered, and the brand reads as insecure. Mature brands use the logo with restraint: in the nav, in the footer, and in a handful of high-impact moments (confirmation emails, welcome screens).
